cheap projector?

I'm looking for a cheap projector. I don't have a TV, and I would rather get a small projector than a TV, if I can find something for the right price. I don't want to spend more than $150 (give or take a few dollars), and the cheaper the better. If I can't find something under that, I'd rather just wait and not get one. I have white walls in my apartment, and am not opposed to making a small screen myself, for portability. I even have access to some polysilk that I could use to make a rear projection screen. In my room, the opposite wall is only about 6' away from my futon, so I don't need something that will make a huge screen. Even in the middle of the day, I can close my blinds, and my room is relatively dark, so it also doesn't have to be extremely high lumens, but the brighter the better. Basically I just want something better than a laptop screen to be able to watch movies on, and hook my xbox 360 up to. Doesn't need to be something truly amazing.

I found this, but it has some pretty bad reviews. Most of the projectors in the $100 range get pretty terrible reviews and it seems like most of them go right from that range up to $250, but I don't know if maybe there's something out there that is decent, and I just haven't found it yet.

Thanks!
