Some of the FD lenses were superb, and you can pick them up quite cheaply now, but I'd forget about using them on an EOS camera.
The best option is to buy a Canon film body, if you really want to experiment with FD glass. I've also heard of people in the US machining the mount to fit EOS bodies without an adapter. It seems to work well, but I haven't a clue what it costs and get the impression it's an enthusiasts project. There seems to be an appetite for this sort of thing in the States, because it's possible and a bit different. Converting Minolta Rokkor 50mm f1.2s is popular too.
