Not that I know the slightest thing about Microscopes and which ones are the most appropriate for electronics work,
but I came across this one for next to nothing, might be worth someone bidding before it's gone.
Not my listing, nor do I know the selelr so buyer beware. (he has good feedback tho).
Just search Item # 350968109962 (Reichert Jung Series 40 Microscope)
Bahh
, someone bid just as I'm typing this. $9.99, shipping would probably be a bargain if you lived in Indianapolis, Indiana...
Just an FYI.
