$109.99 + ship from Frys.com
Limit 1 per customer, so no RAID love for y'all.
Did a quick search, and the SATA seems like a better deal than the PATA (which seems to have been recently FWed @ $100 + ship,) but both were listed in the email I got so I'm passing it along as well, though I'm really only recommending the SATA deal.
Edited to fix links and add retailer info.
