hhmmm, projectors are expensive, i think the cheapest are like $2,000, and those are only like 800*600 resolution. For a good one that you can use for your computer display, as well as a TV, you're looking at around $10,000! and then there's that added expense of lightbulbs, they are not cheap, costing in the hundreds of dollars too.
unless you were asking about those reel-to-reel projectors that you see people watching old home movies on, then those are cheap.
There are a number of different technologies that are/have been used.
All that really matters is:
1. Brightness (lumens)
2. resolution (just rember what the final image size is)
3. Lens/zoom (this will determine haw far or close you can be)
As with everything else, more is better.
What use do you have in mind??

Add to that list "Keystone Correction." The ability to reshape the sqaure of projection. When you project on a slight angle, you get a non-square quadrilateral. Keystone allows you to converge or de-converge the image to straighten it out. Cheap projectors have no to little keystone correction. Mid range projectors may give you 10 - 20% corection. High end ones give you up to 35% correction.
As for a recommendation, that's like asking what is a good computer. How much do you want to spend, and what do want to use it for? Home theatre? Travelling sales demos? A stationary in-office or in-store display?

But I want to know about the different kinds (whether or not I buy one will probably depend on how much I can learn.)
