Subject: RE: [motm] de-soldering help...

Paul's recommendations for construction tools at the back of the pdf
catalogue http://www.synthtech.com/motmcat5.pdf are all good ones.

A 'Solder Sucker'-This is a vacuum de-soldering tool. You'll be doing an
awful lot of soldering, but no matter how careful you may
be, eventually you will need to unsolder something. There are high-end
pedal-controlled electric de-soldering stations available, but
all you really need is something like the Soldapullt model AS196, about $21.
You 'cock' it, then press a button to release a springloaded
plunger that sucks molten solder right up. It has Teflon tips; it will last
a good 5 years if you clean it. Smaller versions are
available, but they just don't have the vacuum of this big boy.
