Looking for a projector for the kids

I am looking for a projector for the kids 3 and 6 years old. It does not have to be high end. They will watch movies, cartoons, and play vid games. I do not need 3D. I don't want to spend a bunch of money. I juest want a descent projector for teh kids. What should I look for in a projector? CRT, LED, LCD, LUMENS, BRANDS? Your help is greatly appreciated.
Thanks
Greg
