PCBs in small quantities are expensive period. 49 is as good as you are gonna do for complete set of Makerbot "Gen4" boards most likely, unless there was ~20 people who wanted sets of them. The fab house I use can get the "3.3 Stepper driver" down to $5.45 each if I was to order 20, but it would be ~30 bucks each for 3... as in almost the same total cost in that area... the problem with the Mak
