Looking for some advice on 4K 3D projectors. Next year I'm considering upgrading my Epson 5010 to a 4K 3D model. I'd like to keep the price point somewhere around $3,000 if possible and in addition to the "usual" pluses in the 4K vs 3K units, I've got to have a lens memory. I need to switch from 2:35 to 1:85 without having to manually zoom the lens and position it left then right and up and down until it fits my screen. This is very important. Recommendations anyone?
