I feel your pain as I am in the same situation with my Sawtooth.

There are supposedly two versions of the Sawtooth motherboard 820-1093-A
(v1) and 820-1094-A (v2). I've been meaning to check and see if mine is the
v1 and, if so, try and find a cheap v2 board.

Changing motherboards completely will probably mean a different PS (to
provide the ADC's 28 volts) and a different back panel (rearranged ports).

I'd say that unless the v1->v2 swap works, then your best bet is a fast
single.
