iPod What is the Best Bluetooth Transmitter?

I need a Bluetooth Transmitter for my iPod Nano.
It will be transmitting to a Bose SoundDock 10 (SoundDock Bluetooth Dock).
it must be A2DP capable.

I've narrowed the choices down to (but I'll take any suggestions):

Sony TMR-BT8IP Bluetooth Transmitter

Kokkia i10s Bluetooth Transmitter

Scosche TZ4 Bluetooth Transmitter

Motorola SYN2837A D670 Bluetooth Transmitter

iSkin Cerulean Bluetooth Transmitter and Receiver

JVC AAT100BT Bluetooth Transmitter
