We like tractors too. I just don't care to see old sewing machines turned into them. I've seen a couple in person and wasn't impressed.
I had to move my 27 out of our living room to make room for a Christmas tree last year and haven't put it back yet. I did enjoy sewing on it while it was set up though.
I just don't use decorative stitches for most of my projects. I don't sew with a lot of knits either. A straight stitcher fills 99% of my sewing needs and I think if most quilters are honest with themselves, they'll find it's rare that they need anything more. If you're sewing with knits then it makes sense to have a machine that will at least do a simple zigzag. I might be wrong but I don't see a lot of decorative stitches being used on a regular basis.
