I typically hate de-soldering. Removing old parts, or re-working a new design can be tricky, as you can over heat a part, damage the board, etc. Well, I've been using a inexpensive manual vacuum tool for months now, and it works GREAT! Cleans the holes out well, and the parts drop right out. The Soldapullt DS-017 is the perfect companion to my Sparkfun variable temperature soldering station.
