Need projector recommendations.

...how often would I watch something in 3D to make this worth the effort? Will there really be that many movies that I'd want to see in 3D while wearing silly glasses? What happens in a few years or so when they come out with a new 3D that doesn't require glasses?

I may just go with the old Epson 8700 UB.

All good questions. I don't have the answers though.

How does the 8700 stack up to the 3100e? Does that wireless option mean a lot to you?

Edit:
8700 $2149ish

3100e $1500ish
