I'm asking my mom for a serger for my birthday, and I need recommendations for an inexpensive one that still works well for small jobs. I mainly want it for small jobs -diaper wipes for the kiddos and household cloth items for us like "un-paper" towels, napkins, and tablecloths. I thought I'd start out with a cheap-o one until I learn to use it, and then maybe eventually I can get a nicer one.
I'd pick a low-end Janome serger -- while I have no qualms about buying a used sewing machine, I'd be a bit hesitant to purchase a used serger (from people I've talked to, it's quite likely people sell sergers because they're frustrated with them -- and have quite possibly not taken good care of them because of the frustration).
On the other hand, if you can buy a second-hand serger from someone you know took good care of it, I'd go for it!
