the older 830 Bernina is a gem also. dependable, mechanical.
I see they are now labeling new ones 830. confusing. it has zig-zag, etc. I think they still sell for $500 though. I have a 1090 about 12 yrs old. love it. if you really want a basic machine, get a vintage Singer 401. zig-zag, lots of stitches, should be able to get it for under $200. advertise on Craigslist, someone may have one sitting in the bedroom.
