Rotary "Summer" Unit GB interest

[Richard L]

The last summer module (v2) was designed to work with the HFS-5 (now discontinued).

Since you are purchasing the H3 or H6, it is only most logical way to move forward. With a direct exchange (at no cost), you will have the latest and I have a spare v2 summer for those with an older system who needs a replacement.

It was silly of me selling the last few.
