Although our tech does all the SMT by hand, looking through a
stereoscope, I have friends that use a USB magnifying camera and a 7"
LCB monitor.  I tested this out and it works great.  Much easier on
the eyes and you have much more freedom of movement.

So use that old outdated PC, pick up a cheap monitor and shell out $40
for a USB magnifying camera..that and a good fine soldering tip and
you're golden. (also, liquid rosin is the key for those fine pitch
parts)
