Oops. Mikeal, I had already posted this (below) before I saw your response to my previous posts. So I am going to leave it because I really thing that SVGA is a good alternative if you can't afford 720p or 1080p, and I am not a fan of used. The problem with SVGA is lack of pixels so if you blow it up too much you get a "screen door" effect. The image looks like you are looking out a screen. As you go up in size say from 90 to 150 inches the more noticeable the pixels if you are sitting fairly close to the image. I am typing this using a JVC 32 inch screen and if I look closely I can see the pixels...move back and not pixels...but rather than go to a smaller monitor I like the size. I just think you get a lot of bang for the buck with any entry level pj. As to bulb issues, the internet is full of horror stories, but the same can be said of all electronics.
I only upgraded pjs as I blew up the image from 92 to 120 to 150. The pixels bothered me, but not the other three members of the family. They were perfectly happy watching tv and movies on a 150 inch image/wall. I would recommend a 720p over the SVGA if you are going big, but I don't feel like I wasted my money. Now I have a 40 inch, 47 inch, 55 inch, 70 inch and a bunch of 32 inch tvs which I bought as"bleeding edge" technology...that was a waste of money.
Before edit: It all comes down to what you can afford, but don't miss out on the pj experience due to budget. In a few years, guys will attack you if you have only a 1080p pj. The Toy story image is shot is my Viewsonic PJD5134 which ranges in price from $300 to $349 on a outdoor 92 inch screen. I have about 600 hours on it with no problem. The Frozen image is against my 70 inch sharp in my family room on a plain wall.
You are in a forum were the tastes run higher than that of the average public, so they recommend the best and there is nothing wrong with that...but, don't pass on the experience due to budget. I really would take the $349 pj over my 70 inch tv any day of the week.
