As a follow-up to this, has anyone bought from Texas Wireless? Here's their store:

Their prices are a lot cheaper, and I doubt there's really a difference in quality. After all, the AC charger that came with my Treo 600 has a high pitched whine whenever it's plugged in (I'm assuming that's a bad thing)... I might buy an AC charger and USB Hot Sync charger cable from them. Both are only $5.99 at the bid price. TTYL,
