Nice bluetooth headset?

[djkest]

I'm looking for a bluetooth headset for my new bluetooth enabled phone. I mainly plan on using this while driving in my car (finally decided to be safe!)

Criteria:
Easy to use
Good volume/clarity
Under $40 shipped (if possible)

I hear Motorolla and Planetronics make decent ones, but I'm sure someone here has experience with some of these.

Thanks!

I found This One (http://www.amazon.com/Plantronics-510-Bluetooth-Multipoint-Technology/dp/B0009B0IX4/ref=pd_bbs_7?ie=UTF8&s=wireless&qid=1199388749&sr=8-7) On amazon that looks decent. Little big.
