Seriously, I think so too. After looking into it, it seems like for the two more difficult protocols (PWM and CAN), there are chips out there to do the work for us (for PWM, there are others aside from the ELM parts, that assume you know the basics of J1850, which we would have to for VPW anyway).
And hey, $60 is still substantially cheaper than the $150 for SG2...
