I'm a newbie when it comes to projectors. However, I'm looking for a used one. I know bulbs are expensive so I would like to stay at the cheap end of the spectrum. The only use I'm going to have for it is for displaying images on canvas for an extended amount of time. (I plan on taking images that I create on my computer and then paint them on canvas) I don't need anything super just something that gets the job done. I would like it to support 1024x768 resolution but I'll settle for 800x600. I would really like the colors to show very well since I'll be painting what I'm seeing. At any rate, any suggestions on how to start looking? What should I be looking for? What price range should I expect? etc. I'm hoping to keep the price below $500 but can understand if I have to go as high as say $800. Thanks for any and all help!
