Emmanuel, I'm not sure if it's one of the latest options or not, but has 
anybody looked at the optiMOS from QImaging?

It has a CIS1920F sCMOS sensor, and everything else looks as good as the 
others but with a reduced sensor size (1920x1080).  It's less that 10k, 
so it's considerably cheaper.  They don't mention the shutter type, but 
it has to be a rolling shutter, right?

Also, there's the Flash 4.0 LT.  I think it's closer to 12k instead of 
the 16-20k of the fastest and global shutter versions.  It's USB 3.0 
which makes life a little easier, and it's got a better QE and less 
noise than the cheaper version of the Zyla 5.5 (which does offer 30% 
more real estate; 2561x2160 vs. 2048x2048 both with 6.5µm pixels).

Does anybody know of a webpage/document out there that has all the 
details and prices in one place?  It would be great to condense all 
these things.

Neil
