[H] Bluetooth GPS Receiver

[Anthony Q. Martin]

Folks,
I'm thinking of getting a bluetooth GPS receiver to use with my UMPC.  My 
software will be MS Streets and Trips 2006, since I already own it and don't 
want to buy more software.  Have any of you used a BT GPS receiver?  How 
well do they work?  I assume I can use any BT GPS receiver with my UMPC and 
Strees & Trips, right?  Does that software suck? (Well, Streets and Trips is 
fine for what I use it for, so as it stands I don't see a need to replace 
it - I just would like to know if it works okay before spending any  money).
Comments appreciated.
Thanks.
