I also recommend just dropping the $10 or so for a PLCC puller, cheaper than a replacement Amiga....
BTW, a while back, an old 486DX I had died... so I figured I would strip the chips out.... one was a PLCC chip, I tried to use a jewelers' screwdriver, and the socket broke, actually more like shattered....
Just a caveat... :roll:
edit: also, IME, those Agnus chips are in there pretty tight
