I've been using a Jabra BT 620 for several months now. Quality is very good, especially for the price. Comparable to my friend's 100.00 Sony BT headset. Here's a link on Amazon:

Don't bother looking in retail stores for a good deal. In-store markup on this type of device is ridiculous. Find something like this on the web.
