I would seriously doubt it. Anything that sounds too good to be true probably is.
However, I'll tell you how to make your 20" TV seem like a 100" screen. Image size is relative to your field of vision. So if you want your 20" TV to seem bigger, just sit closer to it until you reach the desired effect. Best of all, I won't even charge you 30 bucks!
I did hear about an do it yourself LCD projector recently, but that's using an existing LCD monitor screen, not a TV. That'd be about the closest thing I could think of.
I do not see how it can be done for 30 bucks, thats for sure. But if we all sit back and think about it, tube type projection TVs start out with 5" CRT's and through short focal type lens and a couple of mirrors, it ends up to be 50 to 60". This is one reasn a customer will complain about a set looking grainy, and a cable guy will come out and hook up a small 9" 0r 13" TV set, and the picture looks good. But if you look realy close, you see a littly bit of fuzz in the picture, but not enough to worry about. No you take that 5" picture with a tiny bit of watchable fuz and multiply it 10 times! Now you have loads of fuzz in the picture. 10 times as much!
