Sweet!
I've enjoyed the StereoZoom 3 (but never found a boom unattached
to a large pricetag). Wide field eyepieces are a must, I've been happy with these

That looks like the same as the one on eBay. It would be $25 for a
pair,k plus shipping VS $18 delivered from eBay.


but if you can find the 5x ones, get them instead.
Glancing illumination is sometimes better than the light ring, consider one of these

I used a SSZ-7 at Microdyne, and I tried every light source they had.
The ring light was best, for looking for bad solder work, and for doing
rework. It wasn't LED, and had a small gap in the lighting at the ends
of the glass tube. I was hand soldering leads that were .015" center to
center, and any other type of light required constantly turning and
moving the PC board.


This is the microscope that I bought. The seller was sking a higher
price, but they accepted my offer.
