We have GE ImageQuant 500. It's really great.

We have a Biorad ChemiDoc that works nicely as well and also has the capability to image multiplex fluorescent western blotting.

Look into ImageQuant from GE. You can do all sort of things like imaging DNA gels and if you find the filters you can also image fluorescence (WB probed with a fluorescent secondary). We also have the Licor in the lab and is an extremely reliable imaging system. Very good but it requires that you buy secondary antibodies that are fluorescent which can end up being expensive

thank you!  Looking at the prices, I don't think we are quite ready for an ImageQuant or ChemiDoc, since we aren't doing any DNA gels or multiplex yet. 

I'm glad the Licor performs well and scheduled a demo for next week to try with their ECL and one I have already, since theirs seems more expensive than most.

The C-DiGit Scanner is a good and very inexpensive option ($4995). Here's a link to some reviews on SelectScience:

Hi Hanaa, I am the local Bio-Rad instrument specialist in Montreal. I apologize for contacting you directly in this forum, but I could not find your contact info anywhere. Bio-Rad has great imaging solutions at very reasonnable prices. I would strongly recommend a camera based system over a scanner since it would allow you to control the exposure time and increase your sensitivity when needed. Let me know if you'd like to meet to discuss ([email protected]).
