Thanks for the info, Constabulary. It's good information to know, but I'm not really concerned about the stitch length.
At this point in time, it's exactly what Uwe mentioned. I bought a cheap machine to see if I can learn to fix and maintain it...and of course sew some stuff.
Once I feel confident that I can take care of the needs of a used machine, I'll be upgrading!
I'm actually really excited about this.
I'll take some close ups and post them over the weekend.
