Anyway, I'm quite happy with those. Besides, it's color and you can use 
camcorder for your lab occasions and can grab. I used to use it taking 
experiments pictures and ouput through 360x360 Cannon colorjet printer. 
They are almost picture quality but you have to use special paper not 
ordinary xerox paper. I used to make posters for presentation with this 
way. You can annotate whatever you like. Then I sometimes make that into 
slide directly from Powerpoint. They looked beatiful.
I don't think $20,000 gel documentation system can do these. 
Isn't it B/W, that CCD camera?
Actually, that system has same function as frame grabber. Why you wanna 
pay more money for B/W camera? GE has $550 camcorder with high enough 
quality for this.

I mean, it is  much much cheaper even with high performance!!!
