My #1, all-time-favorite projector brand is Eumig. Specifically the 600D-series. Eumig 600d, 605d, 607d, 614d, etc. Why? For several reasons:
I used these projectors a lot in clubs and at dance events. 5 in a row, set at 3 frames/sec. and you don't have to worry for the next couple of hours ;-)

Beware, I never had good luck with the Eumig Mark S (sound projector) series. I always looked for the D!
