Jon,
I have a hakko FR-300 desoldering gun and a knock off of a hakko station. Your
right about general use of the vacuum pump tools, but I need something I can
use when it's not practical to drag my hakko gun around and also when I work on
some disk drives where I can't easily get in to change caps but it's a bigger
hassle to remove the board (i.e. The lamp amplifier board on a persci drive)
So I'm hoping someone has some experience using both of these Soldapullt models
so I can decide which one to order.
Thanks,
Cheers,
Corey
