Bluetooth Headset

I used to have a Bluetooth headset, but didn't find that I used it much. Now however, I have a job where I am unable to answer my phone unless I have a headset. So...needless to say I am in search for one again. I sold my old one, and am now on ebay looking for one that I would like. So far I haven't had any luck...but with time I'm sure I'll find one.
