Hi wildguy!
I'd first suggest you do a search of this forum on sewing machines. This subject comes up at least twice a year.

I sew quite a bit and would recommend:
1) make friends with your local sew n' vac store owner and/or repair guy. Ask about used OLD machines. (with steel gears)
2) you only need straight stitch, with reverse, and zig-zag.
3) Stick with mechanicals. Electronic drive machines are awesome when they work but when broken, you're done.
3) Craigslist is a good place to find good machines. Also, ask folks in your family, church, etc. Many machines are gathering dust in closets and you'll likely get a free one.
4) practice practice practice. You'll learn what you really want and like.

I sew lots of quilts, theatrical costumes, and my own gear. I want a machine that's fast, easy to fix, and will hold up. All my machines are 30+ years old, and none cost more than $150 including my sergers. I stick with brands that have parts available....no particular favorite. Some old machines are considered classics and your sew 'n vac guy will know which ones.
