Can anyone recommend a good bluetooth car speaker that I can use to listen to music on my Sprint Treo 755p while driving?

I found an old message here from 2007 but I am wondering if there are any more current products that can do this.

I have seen some products from Jabra and Motorola but I am interested in hearing from people who have used them.

Also, can the speaker sit in the cup holder instead of on the sun visor? I need to move the sun visor around a lot to block the sun and I don't want the speaker falling off or pointing the wrong way.
