I bought the Epson 6100, and returned it. The defocusing was terrible, and it was very
loud when in high power mode. The Pro8100 is not as bright (brightest mode,) but the quiet sharp picture means more to me. Further, it is very close to as bright in best mode.
The Epson looked very washed out and lifeless. I had a HD80 prior and the DLP had much better color. I really hope the pro8100 has more pop.
I think for $1300 the projector will be great. We are in a new home and the money is spread thin. Once we are settled I will get a new 1,000,000,000,000:1 CR PJ. They get so much better every year!
Also, Tigerdirect put the Pro8100 on sale. $1299
In all of my research, the only knock against the PJ is black levels. I can live with its performance for a few years. I have never had a quiet projector, so I pushed that to the top of my list. I am excited to have a room without a central vac sound overhead.
I will share my opinion of the PJ once it arrives and I get it on the ceiling. I am projecting onto a 100" Stewart Firehawk G2.
Another bonus: Once I am done with the PJ I can take it apart and park my car in the housing. This thing is HUGE!
