I can only recommend the Motic microscopes. i'm very impressed for $1,70O incl camera, not as sturdy as Leica (my favorite) but very good image quality. Drawback: no cold light source. But you can get a gooseneck light and do top illumination. Do not buy their polarizer, though. Cheers, Jens

Hi, I am looking to buy a modestly-priced zoom scope for x-ray crystallographic purposes ($2-3000). Does anyone have suggestions about what/where to possibly find this? I currently have a cheap one that goes from 7.5-50X, but I'd like something with a little more magnification, a better light so
