Just listed this on the page, Thanks.

The ARCSIN seems like a direct competitor to the HobbyCNC board as
they are both 3 amp and 40 plus volts.

Going from the 28 volts of the A3977 chip to the 40 plus volts of
these boards is a pretty big jump in performance for not a big cost.

The other benifit is that both the Arcsin (Buildyouridea is just too
long of a name to call it) and the HobbyCNC board have on-board
parallel port connectors and the savings of another chunk of change
makes them directly comparable.
