It's a 201 - go buy it! LOL!
Actually, it seems to have a knee-lifter mechanism on the back - hard to tell for sure, but I think this kind of 201 is a 1200. I just saw a discussion on these the other day, but I can't remember where.
PS: if you think it's a great price, I would definitely go get it. The 201 is one of the best machines Singer ever made - the 1200 has a knee-lever foot lifter, but they're basically the same machine. Potted motor, class 66 bobbins, standard 15x1 needles. :)
