I bought a White school over buy back in the late 80's when I didn't have much money. Worked great. Made alot of curtains, kid's cloths & alot of dolls (for sale). I used it until I needed a machine with a larger varity of stitches. The person who I had used to clean it said that it was a great buy.
Go for it. Just make sure that there is a warrentee for the machine.
