I went with:
Amazon.com: Seagate FreeAgent Pro 750 GB USB / eSATA External Hard Drive ST307504FPA1E2-RK: Electronics ($242)
Newegg.com - SIIG 6.56 ft. eSATA to eSATA Cable Model CB-SA0211-S1 - Retail ($20.99)
It does seem faster than the original internal drive, especially deletes.

I was watching that one on Amazon too. I got a deal at Fry's a month or so ago so went with that one and an enclosure. $179 free shipping was hard to ignore. I like the performance so much I got the same drive at newegg for a few bucks more but was content the performance to price was good.
