I have acquired an older Babylock serger - it is missing the telescope yarn guide and needle clamp, has a little rust for $40, my plan was to take it to a repair shop and see $$$$ to get it in working condition. Can't check the loopers are in sync till I find a needle clamp but motor sounds good. I find older machines are usually well made and sturdy. Any input in what is reasonable to get it repaired or should I just by a new cheaper brother? I hear Babylocks (especially some older models) are great.
