A lot of people ask me about projectors and projection screens with the most interest being about Rear Projection Screens. I'm all for anything that saves money so when I saw these twitter posts from Mark Jungmann (@NorthPolkWestPE) and Mike Graham (@pe4everykid), I knew it was the jackpot. Here's a look at Mike's ultimate creation which he said he was able to make for under $20. He used a frosted white shower curtain (frosted is the key!), PVC, duct tape and mini bungees to pull it tight (and couple of L brackets to attach to the backboard).

Below is Mark's setup:

Also, for information on projectors here's an article by Kevin Tiller (@physedreview): goo.gl/h6p5rg & video reviews of 2 specific projectors: https://www.youtube.com/watch?v=yGTjFtmNquI & https://www.youtube.com/watch?v=jtpqdOKwmTA

Selecting a projector is very specific to the particular "space" you will be using it in. There are 3 types of projectors: regular, short throw and ultra short throw. Generally, the cost goes up moving through those types. Another factor is whether you are going to be "ceiling mounting" it, or using it on a cart on the floor. If on the floor, you may want to use a short throw or ultra short throw so it can be closer to the wall thus resulting in less cord "trip hazards". One "problem" with an ultra short throw is that you usually can't project high on the wall with those, so if you go with that, you'll need a large "projectable" space where the bottom is about 8 feet off the ground. If you need to project higher on the wall, you'll need a short throw or a regular projector. Some people choose to project onto a screen on a stage. If this is the case, how far back your projector can be from the screen, will determine which projector type to go with. It's a good idea to talk with you IT staff about the options for projecting as they, probably, are familiar with at least some of the possibilities.
