Just thought I'd share some feedback on a great cradle I recently got on ebay.
It works great and unlike many I've seen out there isn't just a phone holder that then requires you to plug in the usb cable yourself. The usb is actually built into the cradle.
There's a couple models, I got the one that charges an extra battery just in case I ever need to have a spare charged and ready... but there's a phone only version as well.
Not sure if it's okay to post links here so I'll refrain, but if you're looking around on ebay for one here's a couple pics of the one I got:
(it comes with the data cable and charger as well)
