Hi there, I am always intrigued by the thought of a cheap video projector.
I looked for a $75 proj at bestbuy, and did not find one.

I did see one for $179, with a native resolution of 854x480.
This is a pretty low native resolution for a modern video projector.
(Native resolution means the top number of pixels that that projector is going to project.)

some examples of resolutions:

320x240 ipod classic screen
640x480 vga 4:3
720x480 ntsc 4:3
800x600 svga 4:3
1024x768 sxga 5:4
1280x720 hd720 16:9
1920x1080 hd1920 16:9

native resolution and lumens are the main things to think about in regards to what you want a projector to do.
I can take my ipod and project it through a hd projector, but it's not going to look good at all.

What you cannot do is take a high resolution source and project it through a lower resolution projector. The projector cannot handle the additional data, and you end with a digital mess on the screen, that is not showing your source. you'll have to change the output resolution of your source and that can problematic for many reasons.

there was a sharper image brand video projector that I bought once for $50.00! I was stoked because the pics on the box showed a decent projection.
Not at all, it was not bright, didnt focus well, and there was this internal screen that projected a dot matix on top of the image.

So anyway, my point is you get what you pay for.

Just to let you know I saw a video projector for sale at Best Buy for 75 dollars. It may not be high end but I intend to buy one ASAP. Online they maybe even cheaper.
