The machinist that is doing the work on my motor ordered a few sets to get the price down, and then charged me cost for a single set. I think I paid $500 even for the set. I got my JE pistons from him too. Those cost me about $575 for the set cause the shop bought like 48 of them at one shoot.
I don't think you could get the same price from him unless he does all your machine work.
