Jim has been super helpful over the years. Let's take up a collection. I
could spring for $25 if we could get 40 others to contribute commensurately.

Would be great for getting a better look at the bits wanting resolder
That does look intriguing, but the budget is a bit tight
at the moment!

--------------------------------------------
There wasn't any information on the WU 'scope that I could find. I don't
know how much experience Jim has had with microscopes, or if he wants to
solder while looking through the 'scope, but there are scopes with higher
magnification that wouldn't work too well on the top side of circuit boards.
Bottom sides would probably be okay. I've tried to use clinical 'scopes
(400 to 1200 diameters) looking for hairline breaks on circuit boards, but
they focus so close to the objective lens that the board components get in
the way as does the goose neck. I would think a dissecting scope with lower
magnification and deeper goose necks might be usable since you have more
room under the objective. The 'scope in the picture seems to be equipped so
that two persons can look through it at the same time.
Used, rebuilt, and even new microscopes; both of the clinical and dissecting
type can be had for quite a bit less than $1000.

...or plug "used microscopes buy" into Google.
If you want to learn about different types of microscopes plug "types of
microscopes" into Google.
