I have an Epson HD projector. It does 1080i or 720p and barely makes any noise. It cost me right about $620 with shipping and I could not be happier. I watch Blu-Ray movies from my PS3 on it and they look outstanding. I would recommend this to anyone. It sits in our living room and, while it is tough to deal with in daylight, you watch most TV and movies in the evening or late at night. Good points in your article, but if you have the space for this (they require fairly large rooms) I would definitely recommend it over a conventional LCD or Plasma!

some business-class projectors make great low-cost home theater projectors. I have a Sharp XR that displays avery nice "720P/1080i" image on a 92" screen. The projector's native resolution is 1024x768, and it does scale the image some to reproduce 720P/1080i - but I can't tell the difference from a native 720P Epson. It has component and DVI (but no HDMI). I use a DVI to HDMI converter. since my 5.1 is routed through the reciever that isn't a problem. The Sharp XR-30X is under $600 in some places. Great picture for the price.

Well, I currently project mine onto a plain white wall. The same kind of white colored wall that you can find in almost every house. It looks great. With a screen it does look a little better, but if you don't want to spend $100 to get a decent screen, just find a white wall. No need to paint with special paint or anything.

Well, if that is the case, then you would definitely want to go with a screen. My friend has light orange colored walls and therefore he bought a 100" pull down screen which he suspended from the ceiling. I would say this issue only pertains to each persons individual situation. Obviously you aren't going to want to project an image onto a flower covered wall or some other crazy random wallpaper, but if you have a white wall, try it out, see how it looks. Maybe you decide you don't like the image, then go buy a screen, or go buy projector paint (which is relatively expensive). It is completely up to each persons situation and taste and can only be decided by that person.
