For soldering, use the Metcal STTC-090 tip
($27.78 from Mouser SKU 745-STTC-090)

0.25mm tip diameter, perfect for 25 mil pitch

BE SURE TO GET THE WS1 AUTO-SLEEP WORKSTAND
TO SAVE THE TIP!

For a microscope, check out "AMScope".
You can buy just what you need.  I got
a completely tricked out setup including
a USB camera that goes to a third optical
port for only $600.  A basic scope might
only run $200.

Scope buying advise: get a 0.5 power objective
lens so you don't have to be so close to
the workpiece.  Also use somewhat lower power
eyepieces to get a bigger field of view.
If you need a lot of power once in a while,
get a 2nd pair of eyepieces to use on those occasions.
