@PaddyBarco F90-W13 could be a contender once the 0.28:1 lens is shipping in Quarter 3 2017. There is also gonna be a new ultra short throw lens for the TLD range which works with the HDX series of projectors.I think Epson also has ultra short throw options available for the new laser...
We got good results on this side of world with silverstar frezno ZE-03 over here. Installed a couple of venues and no failure till date. The fan can run a little noisy though but with the brightness output, i think its a reasonable trade off.
