I have a pro triplet in great shape (never actually used) and a pair of fresnels that have been sitting around collecting dust that can be put to a lot better use by someone else.
The fresnels were cut to fit a 15.6" widescreen lcd and measure 15.25" x 11.5" - they are in a holder made of mdf and aluminum, they are setup in a non-split orientation that allowed for easy adjustment. If you don't want the holder just let me know, I could find some use for the aluminum.

The yellow "ooze" is where the gorilla glue expanded. They were set to be in a vertical orientation and the holder will ride on threaded rods. I also have an LCD holder set to fit the 15.6" (which broke) that I'll throw in if you want it.
