Thanks Tartan! My Featherweight belonged to my mom, so it has sentimental value to me. I had to use the manual it came with to learn how to thread it and oil the machine. I even use my mom's thimble, seam ripper and ruler! It also sews a very good straight stitch.
Realistically, my budget should be pretty low, $300 to $500. If I was young, I might buy a fancy thousand dollar machine, but I'm not that young or rich! I saw some great prices on Amazon. The article I read recommending buying from a sewing machine store rather than Amazon. That way I would get hands-on training and follow-up. I am such a you-tube nerd, that I'm not sure I would take classes.
