I followed the same path to be able to work with SMD at home. Found a 
binocular microscope at a hamfest, guy was sellling a bunch of old 
style scopes from Intel factory nearby. Mine had a loose eyepiece 
(whatever you call the little lens assembly that fits next to your 
eye) so I just put a small rubber band around it to stabilize it. it 
was <$100 US dollars. I also got a Metcal RF soldering iron for about 
$25 from a local junk dealer. Had to replace the cord and handle and 
tip. They are wonderfully designed units when they are working. Mine 
has an occasional intermittent. Inside of Metcal stations there is a 
13.56 MHz crystal and a power amplifier to drive a small induction 
coil heating the tip. The cord is a special flexible silicone coaxial 
cable!
