Need help choosing a projector

[Brent H]

Hi,

I'm looking to buy a used projector and have three that are within my price range.
I need the projector to deliver PoewrPoint preseantations to groups of 40-60, using a screen up to about 10 feet wide (at most).

My options for used projectors are:

1) Epson EMP 730C HDTV Projector (2000 lumens) - $750
2) Optoma Multimedia Projector (EP 739) - $600
3) Infocus LP330 Projector - $575

Which would be the biggest bang for my buck?
Any lemons here?

Any advice would be greatly appreciated, since I have no clue what I'm doing.

Cheers,
Brent
