I'm leaning heavily towards the 3rd option, it’s the cheapest, and I’ve heard good things about DLP: http://www.dlp.com/

Beware of the DLP rainbow effect!
What is the Rainbow Effect? The DLP 'rainbow effect' is an artifact unique to single-chip DLP projectors. The artifact appears as a rainbow or multi-color shimmer briefly noticeable when changing focus from one part of the projector screen to another. It appears as a secondary image that appears at the viewer's peripheral vision and is generally noticeable when shifting focus from a high contrast area or bright object.
3-chip DLP projectors, higher wheel speeds, 7-segment color wheels, and archimedes color wheel designs (pending) are minimizing or may altogether elminate the effect. Make sure you condier the specs carefully before you buy DLP. If you end up seeing the rainbow effect, you'll hate your TV.

Thanks for this, I wan't aware of it. I went to a zillion stores last weekend and squinted at various TV sets. Saw no rainbow effect. I guess some people see it and some don't? I am hoping I will be able to somehow audition a set in my space before buying it.
The main reason I'm considering DLP is that my current set has things burned into it from gaming. I am not responsible about this, and I don't want to ruin my brand new exciting set the first time I pass out in front of the TV with my game paused. As far as I'm aware DLP is the only option that prevents burn-in, true?

I went and looked at a bunch of sets. I was surprised at how little difference there really is in image quality between the formats, it seems to have more to do with brand. But I still prefer DLP for the no-burn in reason. Here's my first choice so far: http://www.dlp.com/home_entertainment/home_entertainment_product_detail.asp?id=856
