I bought a Curve on Ebay for a pretty decent price several months ago, needing to get away as fast as I could from the WinMo device I was given and waiting for the 9650. I typically look at the completed auctions, target about the 20th percentile sale price, and am patient for a few days. There is pretty high turnover on Curves so it didn't take long.

As I bonus, I get several photos and other personal info from the seller
