The major problem with the SNAPPY is the software which allows you adjust
the image only AFTER it is snapped. To get decent images from low-light,
fluourescent signals requires the ability to pre-process the image.
Otherwise, the grabbed image may not even contain the features of interest
and, if so, no amount of image processing will reveal them.
There are many decent cameras/grabbers on the market from under $1K and
up, depending on spatial resolution and bit-depth. The best way to
determine what you need is to try a few vendors, emphhasize that you do
not have infinite resources and get a demo to insure that it will do
exactly what you need. Oh, and read as much as you can.
