Microscope for Silicon Inspection / Decapping

Could anyone recomend a microscope for silicon inspection?

If interested, take a look at my website for decapping resources. I've collected quite a bit of information on the subject. Comments/suggestions welcome. Join up if you want. Link is below...

Is there anything I should be aware of?

I want to get crystal clear images of the silicon. Here is a 20 mega pixel example of what I can get by holding my digital camera to the eyepiece. Its fuzzy on the right because I had to "aim" at an angle into the eyepiece to avoid strange hazing. Warning...2mb JPEG

I'd like to also find a cheap indexing head, even if its only one axis. I'd like to take a picture of a 68000, 6502, 8088, etc. I think it would be fun to have the whole die on a 30x30" photo at 300dpi.

Thanks, Grant
