I know nothing about projectors so I'm looking for some advice.

For those of you who have them what projectors/screens are you guys using?

What do I need to know about screens? What are the pros and cons of White vs Gray?

The HT room I am beginning to plan is 13'x15' The. The distance of the projector to the screen will be 12' I would like to have a 100" screen. Can anyone recommend a decent projector for around $2k? Thanks in advance.
