I bought the RFD900+ radios for my Reach units last year. However, ReachView 2 is now supporting the LoRa radios that are built in to the new Reach RS. We have been doing some testing with good results and Emlid is soon going to offer the LoRa radio for sale in the web shop. If you can wait for them to become available, then you will likely get better software support with the LoRa radios.
