i buy the cheapest kits i can and swap out the parts i want to use. for my personal builds i basically keep the rod, the piston, the case and port out the jug, the rest is replaced. even buying the cheapo kits for my family, which i just change the gudgeon bearing out on for a wider one. never had a problem with a $50 full kit, except tht stupid tiny gudgeon bearing they use. when tht needle based bearing goes, it takes out the whole top end.
