Sources of Brake disks, chains, sprokets?

[ManDownUnder]

Are there are any good suppliers of generic bike parts that you guys/gals/aldies and laddies would suggest?

My RF is in need of a new rear brake disk and I can see the day coming where the chain and sprockets need looking at too.

I know there must be engineering outfits that specialise in this sort of stuff, rather than buy legit Suzuki parts - but the questions are - are they cheaper, are they better... and are they worth it?

Sources of "generic" bits, comments and experiences wanted.

Motomail should be OK for those, chain and sprockets especially, not so sure about disks. Should be cheaper if not OEM.
