I have a Jabra BT250v. I love it! It was a bit weird learning how to hook it over your ear, but once I had it in place it doesn't come off, and I have hair that covers it. (Which is bad because then I REALLY look like I'm talking to myself!)
I haven't owned any other bluetooth devices so I don't know if I can rate it on the scale. All I know is that it's loud enough for me to hear while I'm driving, fits well, and is easy to use. Looks like amazon has them for $68, I think I spent $78 on mine. Doh!
