I'm taking a chance here. Do any of you girls know this type of machine and could you give me some reviews on it??

I am in the market for a S/H overlocker/serger for home use and I can get one like this REEEEELLLLYYYYY cheap. It's about 19 (eeek) years old, been used only for three (if you trust the seller) and has been serviced Would you buy it?

TIA
