If I understand correctly you have implemented a digi algorithm that
is superior to UIDIGI, so who cares where the UIDIGI source code is?

The T2 at ~US$100 is a reasonable data point, and I suspect an ARM
based unit would be a bit more.

On the other hand, a microcontroller add-on for a KISS-only KPC3 could
probably be built for roughly the price of an OpenTracker, which is
half that.  Hams are both cheap and loathe to let go of any equipment
that they already have. (:

Having said that, a typical 8 bit microcontroller probably doesn't
have enough RAM to implement this.
