Projection TVs - Help needed!

[Siniroth]

I need some help regarding projection TVs.

Okay, first off let me say I just recently decided that I was going to get the new 50" Panny V10 Neo Plasma (which comes out in May). I was all excited about it and everything, but for all that time it took me to settle on that one model, I started reading through a couple of threads in this forum about PJ TVs, and I'm already feeling the dreaded "buyer's remorse", even though I still have several months yet to even purchase the TV!

I had looked at a few galleries of people's PJ set-ups in the past, always jealous because I'd never be able to afford something so big. But then I started seeing some pricing, and I realized, that pricing isn't too much more than the $2k or so that I was/am going to shell out for a high-end Plasma! Considering I don't know anything about PJ TVs, I thought it couldn't be possible to be able to get those crazy 100" screens for a decent price. How is this possible? Lol.

Anyway, I'm starting to really second guess my decision to go Plasma, and am instead thinking about a PJ. Few things I want to ask about though (please excuse my noobish questions :P):

-What is the difference between front and rear projectors?
-What is DLP?
-Why do I see 'LCD' on some of projectors I've looked at. Isn't LCD just the Flat-Panel TVs (similar to Plasma)?
-What is this 'CIH' abbreviation I keep seeing?

Now, I'm moving into an apartment later this year, so no, I do not have my own house. An apartment is what I'm going to be moving into, so Idk if this will be big enough for a big 100" (or so) screen? I'm hoping to find an apartment with a basement, because that would be the only logical place I could think to use as a 'home theater room' with a PJ.

If I decide to go this route (getting a PJ), then I'd just buy a screen. I'd feel much more confident in getting a pre-made screen rather than me having to paint myself one.

Tbh though, either way I'm most likely going to get the 50" V10 Panny Plasma I mentioned earlier no matter what. So I guess I'll have to get both over the course of the next year. The Plasma would probably be in my living room or bedroom, with my DirecTV HD-DVR and my game consoles hooked up to it, with the PJ being mainly used for Blu-ray movies.

That is, if I decide to get a projector. Does a solid projector look as good as a higher-end Plasma (like the new Panny I'm going to buy)? Because I'll want to watch Blu-ray on whatever looks better.

Any help you have, whether on these specific questions or anything else you think I should know about PJs, I would really appreciate.
