[Dxbase] Yaesu G-1000DXA interfaces

[Ron Stordahl, AE5E]

There are a number of available interfaces.

Easy-Rotor-Control e-shop
EBay: Rotor control for G-1000DXA
as well as Yaeus's own which appears to me to be tremendously overpriced.
I have an old Idiompress card which has failed.  I have tried to contact them to see if it would be practical to repair, but no response has been received as yet.
The ERC-Mini DX from Easy-Rotor-Control has a built in USB interface which I believe generates a virtual Com port which should be compatible with DXBase.
Does anyone have any experiences with any of these interfaces with DXBase?
