I find the using the smt rework station to preheat the board, and then using the solder sucker plus a iron gives me good results.

I use a $5 spring-loaded desoldering 'pump' myself. With a bit of practice,
just as good as any fancy-schmancy desoldering tool. The trick is to use
*enough* solder; some people seem to think that because you're trying to
remove the solder, starting with less is better. But the exact opposite is
true - generally you need to *add* solder before you start.
I'm about to attack an Acorn A3000 with a half-dozen 32-40 pin sockets that
need removing. Not looking forward to it, but just got an SMT rework station
so may try to put that to work on it...
