You should try the highly adventuresome but very effective Chinese parts recovery methods.
You pour a good pint of peanut oil into a large frying pan and slowly heat it to a solder melting temperature and immerse the board within. Then with a final stroke of bravado, once you can see the solder melting and flowing on the board, you grab the board with a pliers and slam it down on an awaiting Chinese newspaper and all the ICs and all the parts, IC's resistors, etc, just fall off the board thanks to the G forces.
I am not kidding. I have seen this done. The parts come out shiny and clean. Much of the "Pulls" IC's that were available on the web were recovered like this at one time.
Watch out for fires, even peanut oil can catch fire, make sure an exit is handy, and sooner or latter you have to deal with a few small burns, be sure to borrow an asbestos suit and above all, wear gloves and glasses, but you got to do whatcha gotta do to make a buck in this world.
The persons I saw doing this didn't ware anything but an apron.
