Need help with front projection TV on a budget

My search for the right TV to complete my home theatre seems never ending. I was only considering HD rear projection but I'm intrigued with true BIG screen TV front projection. I have a dedicated theatre room that is 15 feet by 25 feet (I can completely control all light). I would love to have a 100" screen but I've heard a lot of negative stuff about projectors in my price range. I have budgeted $3200 for the TV and I've heard decent front projectors are several times that much. If there are good units out there in my price range I'd love to know about them. I've heard of headaches, rainbows, and other nightmares that I'd rather avoid. For my budgeted price, I'll need the projector, mounts, and a screen...a complete package. Is it worth trying front projection at this price? I'd hate to spend my money and not see the picture quality I want.
