GPS Bluetooth Receiver for HTC TyTN - which one to choose?

[bananasplit]

I'm recently considering buying a bluetooth GPS receiver for my HTC TyTN. I would like the receiver to be as small as possible, fitting either a jacket or jeans pocket, not too bulky, but has good performance and battery life.

I was considering the OnCourse 4 (other sites call it the Wondex BT-100Y) and the Visiontac VGPS-700. Which one of these (based on your read reviews and/or user experience would you recommend? Or is there another receiver that you would recommend meets my initial criteria?

I am London based by the way. Thanks.
