I can't vouch for the 6110 model in particular, but if you are looking for stretchy stitches and single needle overlock type stitch you have to accept plastic gears. All metal models are nice and an advatage, but some of my favorite zigzaggers have a few plastic gears (Elna Supermatic, Bernina 730, 830...) and they have been well worth the money and effort to fix them up for regular use again. Some of these machines run well for decades with out any trouble. If the 6110 turns out to be a good model $28 is not much at all. I expect to spend a bit of time and money on cleaning, replacement parts like belts, bobbin tire, the replacement gears we get now are quite good, sometimes there is a metal version of them too.
