I be in the market for a cheap projector to use for movie until I have the money for something worth spend a lot of money on . I start off buy the Discovery Wonderwall projector for $ 70 and then promptly return it as the image quality be very poor -lrb- I could not read subtitle -rrb- and it be not bright enough to project a dark scene -lrb- e.g. the cave see in lord of the ring -rrb- even in a totally dark room . I then get the pt100 and feel that it work very well for be under $ 200 . it be a clear enough image that the subtitle in a movie be easy to read . however , when hook up to a pc the word on the desktop icon be not clear enough to easily read . it be bright enough that about 90 % of the detail can be see during dark scene -lrb- e.g. the cave see in lord of the ring -rrb- . it do need to be use in a dark room to have any quality . I would say the image quality be similar to VCR\/analog tv with the benefit of a small , lightweight package that be versatile and can project a large screen size .
