Gel documentation and imaging systems

[Jan van der Ploeg]

Hello,
This question has been asked before in the past, but I would like to know
which system for gel documentation and chemiluminescence imaging you prefer
to work with. I have been looking at Bio-Rad's Chemi-Doc, Alpainnotech's
Chemiimager, the Chemigenius from Syngene, and the Chemi system from UVP.
How important are camera resolution and amount of grey shades for
documentation of DNA gels, protein gels and blots?
Thanks, Jan
