The Singer 99K

 If I had to choose between a model 15 and 99K, I would take the 99K, because I like the drop in bobbin feature. Way easier to take out and replace the bobbin. (almost sounds like like I actually know how to sew, doesn't it?). On top that that they are just plain pretty machines. They sew very quietly when they are in good condition, but for some reason Singer made them to be a fairly slow machine by giving them a large diameter sheave on the balance wheel. I have swapped out the balance wheel on some and they run a lot faster and they seem to sew just as well.

There is an interesting lesson to be learned from this one. How do you keep your sewing machine in great shape? Simple, break it, don't fix it and shove it in the closet for years and years. The lady that I got this one from had a problem with the tensioner, and since she had a model 15, in a table that she preferred to use, she never really used this one. She gave it to me, when I bought her 15, just so it wouldn't end up being recycled, and I promised her that it would go to someone who would love it and use it, which it will...
