I've had one of those behemoth Zenith front projection TVs for several years now, and finally felt the urge to move to something more modern and smaller (you get claustrophobic with that thing literally hanging over you....
Looking at an InFocus 7210 DLP unit - been out long enough to have any kinks worked out and to drop in price to a decent street level.
Is there any reason to go for more than 720p?
We are talking about a 100" screen (yes, I know 106 is more normal, but 100 was what there was space for once I got my speakers aligned for perfect non-video listening)
Follow Ups:
The upconverting DVD players like Oppo do it at 1080p, and then only over HDMI -- and the results can be gorgeous.

They will also upconvert to 720p so upscaling players aren't a strong reason in my view.
There is one substantial reason, and a possible second reason to seriously consider 1080p if it's affordable.
The substantial reason is that it's the native resolution for the high def formats and a lot of hi def TV is broadcast. You aren't going to lose any resolution from the best current sources with a 1080 p projector but you will lose resolution with those sources by using a 720p projector.
The second reason is a maybe, it may or may not be an issue. You haven't mentioned your viewing distance but at close distances you will pick a visible difference in detail between 1080 and 720. At a slightly longer distance you won't. I forget the formula but it's certainly findable on the web. If your viewing distance allows you to see the difference, then 1080p is going to be a visually worthwhile improvement. At longer distances you won't see a difference unless there's some loss introduced by a poor quality rescaling of 1080 material to 720p.
Really, you can certainly argue that 720p is good enough if you're not sitting close enough to the screen to see the difference with 1080p but the 1080p machine is a little more 'future proof' and you may move to a different home and end up with a room in which you can see the difference and you will already have the projector.

Obviously an Oppo peculiarity. My Denon DVD player, the 2910, and the Pioneers I've owned have all offered upscaling to 720p as well as 1080i or p, and offer it with analog output as well.
Probably one of the ways that Oppo cuts costs and not a bad way to cut it in many cases.
I've got an LCD screen with 1366 x 768 resolution and find upscaling in players and receivers unneccesary. If I let the player or receiver upscale to 720p, the TV is going to rescale to 768 in order to display the picture so I end up with rescaling on an already rescaled image and that either looks no better or slightly worse than simply sending the standard def signal to the TV and relying on a single rescaling process.
In general I'm unconvinced about the inclusion of rescaling in players and receivers.

It probably depends on the respective qualities of the display and the player, and with a budget upscaling player I can well imagine that a display's upscaler would give better results.
My own Denon however upscales to 720p and 1080i, and when I leave it to output DVd at it's native resolution so the Panasonic PX60 does the scaling the results aren't anywhere near as good as when the player does the upscaling.

I found good upscaling players do a better jo than my Sony SXRD as well. I suspect this is an area were TV manufacturers cut corners.

As a general rule, upscaling isn't allowed via analog outs. While there are a few exceptions, here in the US it has to be done via digital connections. Its been decreed by the DVD Consortium. Perhaps things are different where you are, as in the case of region coding.

My 2910 only upscales on digital outputs.

Check the reviews at www.projectorcentral.com. IMHO, the projector to own at 720p is the Panasonic PT AE200U, but that is $1300 Excellent brightness and color saturation even with ambient light, loads of flexibility in terms of placement because of the 2x lens, and easy lens adjustment with a toggle, a complete lack of visible pixelation even close up, and two HDMI ports. It also has a reputation of being among the best in makling standard definition 480p DVDs look sharp.
On the minus side it's bulky at 11 lbs, and costs as much as $500 more than the least expensive 720p unit, which can be had for about $800.
1080p only makes sense marginally if you are going big time into Blue Ray or HD DVD.
Broadcast HDTV is either 720p or 1080i, and a 720p projector should do both of those well.
Read the current thinking on 720p vs 1080p on the projectorcentral Web site. Right now expect to spend upwards of $2000 on a full 1080p projector, tho I expect these prices to drift toward the $1500 level by the end of 2008.
For projector, check out JVC Pro. The RS1 @ $5.5K & the RS2 @ $8K. They are hands down the best bang for the dollar projectors I've seen. The only projectors that compare are $30K+ Vidikrons and Runco's (and I think the JVC Pro out performs some of these models).
To calculate maximum screen size (for 16:9 ratio), measure (in inches) the distance from the screen to where you'll be sitting and multiply by .71 . This is the maximum diagonal size your screen should be.
A lot depends on how close you are sitting to the screen. 100" is fairly large...
I'm certainly not an expert on projectors, but if you are shopping around, you really should look into 1080p at this point.
