Vintage Singer Featherweights or Singer 301's are super machines for straight stitching. You could find a featherweight for around $200 to $300, or a 301 (or 301-a, they are the same), for around $75 to $150. Shipping is never good for a machine, but these two machines can be shipped, and are readily available on that auction site. Also, they are fairly common finds at estate sales. Have you tried Craigslist? You can maintain them yourself, but if you don't want to, you can have them serviced at any sewing machine shop for minimum charges. Vintage machines are the only way to go, IMHO. The newer machines are just too "flimsy" for me!
