Looking for DDR help

Ok, so I managed to snag some appallingly cheap deals on extremely good DDR pads for home (metal fittings, nonskid bottoms, 2 inch thick materials, blahblahblah).

Anyway, I know I'll need a mod chip for it, and I've found one that's one of the kewl no-solder ones, so now I need to start finding the DDR series ISO's so I can start really playing. Anyone point me in the right directions?

Christ!

It's like the answer to a prayer or somethin'. Ok, maybe not, as I really can't afford them still, but for those that do need extra storage space, or HD's have gone bad....

I happen to love Western Digital drives as they tend to be more reliable, at least to my experience. But, if you're a Seagate or Maxtor believer, they also have listings for those, at nearly equal prices.
