should I purchase an older Babylock serger?
I have an opportunity to purchase a serger. I've never used one before. It is a 4 thread Babylock BL4-736DF with a differential. Is this too old for a beginner serger to use? Is it worth having a sewing machine repair person look it over? What kind of $$ is it worth in todays market, presuming that it is in good working order? I have looked on the internet and there is a manual available but there are no reviews of the machine? What was it worth when it was new? Thanks in advance for any advice.
