Gel Analysis System

[Dietmar Rescheleit]

Hallo!!!
Who is able to tell us some information about commercial gel documentation and
analysis systems e.g. scan pack from biometra, image master from pharmacia, gs
XXX from biorad or other systems (with camera and scanner). we would like to
buy one and search for the best system in thin layer chromatography, PAGE and
Agarose gel documentation, quantification and moleculare weight calculation. 
Thanks for answers
