Anarduino Miniwireless vs. Lowpowerlab Moteino

I am looking for a pair of transceivers (on a Arduino board) with a RFM69HW. At the moment I found Anarduino Miniwireless and Lowpowerlab Moteino.

Which one is best? And are there other vendors?

For my application I need reliable, low bandwidth communication (9600 Baud), range is approx. 300 meters.
