Got this off of Ebay from Cellbatt. $18, if I am remembering correctly.
I'm sure most of you know about this little device. But, for those who do not, it is a really handy thing to have.
What you get is just the cradle, so you have to use your own power cord. It works with either the USB or electric cord that came with the Tour. The gold colored metal contacts that you see match up with the contacts on the back of the phone. You don't have to take off the battery door. It also keeps you from having to plug the phone in all the time. Just drop it in and you're good to go, the phone is charging.
Here's some pics I just took of it, sorry about the dust :
Bottom has rubber on it, no slipping around.
Notice the little light on the back. Handy in the dark...
