I had narrowed it down to the Jawbone ERA and the Plantronics M1100
I went directly to the Jawbone forums and read tons of complaints about sound although all the retailer reviews raved about it. It is $99 at Best Buy but will see online as high as $129
The Plantronics M1100 was $79 at best buy but I found online brand new in retail package for $45. It had as good of reviews as the ERA so I thought I'd try it first. it's really great, sounds good, I've asked and nobody knew I was on a BT - it comes with a year of Vocalyst which is plantronics branded version of Dial2do. For the free service for a year, you can have email read to you, post to Evernote, make reminders, send email, listen to twitter, post to twitter, listen/post to facebook.
Hope this helps..
