My first serger was the Necchi Pro Lock PL1026. It was a small workhorse for about 12 years until I had a problem where the needles wouldn't lock into the needle holder. In '08 I took it into the sewing machine store where I purchased it and they told me that they didn't have parts because the company went out of business some time ago. It is useful if I really work on securing the needles but I had to replace it with a computerized Viking (big mistake there--wish I'd bought a Bernina). Just be aware parts might be hard to find for them. If they are in good working order and the price is right, go for it!
