i have a small bench lathe and mill which i one day,several years away, intend to convert to cnc. with prices rising with time, i plan on buying my steppers and drives sooner rather than later. the question is, after ebay visits,should i buy from the us or canada, or are the kits out of china worth even looking at. as i said it will be some time before i install the kits and dont want to through away my money.
