One of my reasons for taking it in is because it does have a small problem - the locking stitch doesn't work. In addition, I bought it off of eBay, so don't know what kind of care it has had. I do appreciate the "devil's advocate" comments - it's always good to view things from both sides. I'd rather be safe than sorry though, 'cause I couldn't afford a new machine if I burned out this one. :cry: I do all the maintenance on my Featherweights myself - but when the Elna is encased, I really can't tell where the lint goes or what else might be wrong with it's innards. I really appreciate all the responses. You guys are awesome. Now I'm going to check with my Guild buddies to see who they recommend taking it to...and am somewhat braced for the cost.
