Also there no LP category. Only HP, so M2 is not a wise decision.

I know 3 devices:

1) 4o3a

http://www.4o3a.com/index.php/products/station-automation/lock-x/

and for inband use

2) ea4tx

3) Acom

http://www.acom-bg.com/products/xcvr-commutator/acom-2s1-automatic-xcvr-commutator

Acom and 2nd 4o3a are for inband use. With Acom you can share the same 
antenna, with 4o3a you need 2 antennas (better but you need one more ant).
