Barring eBay as a possible purchasing site is a bit extreme. Maybe we should say use extreme caution and obtain as much information as possible before making the purchase.

I don't have a BT headset; I just can't get excited about a single earpiece. However I did see a Motorola display stand at Fry's last weekend for a BT stereo headset and a microphone, allowing dual use for phone conversations and audio playback. Unfortunately, Fry's had no working models, only pictures. But it did perk my interest especially now that I have a brand new empty 4GB mini-SD card sitting inside my Treo.
