Not really a group buy, but, I'm going to order some of the peak and hold driver boards from JBPerf.

If you have low ohm injectors you are running with resistor, or are using the crappy noisey PWM current limiting that B&G provide, this IS your solution. This is just to see if anyone in the San Diego area wants some - shipping's only $5 anyway, so I'm just doing it as a favor not to make money. LEt me know, I'm ordering them by monday. They are whatever they cost, I think $18.
