Good idea to pass on that one. 201s are not rare. Yes, they can be used without a base, and you could pick up a plastic case to hold it, but that's more money for a machine that should be whole and the drawers full of goodies at that price.
I picked up a lovely if well loved 201-3 (or 201K) for $22.50 on sale at the thrift shop last weekend. They were having a half price sale. It came with a buttonholer, all of the attachments (no screwdrivers though), the box and the manual. There were no parts of the machine missing. The #43 cabinet needed some work, but I've done all of it (plug and re-drill the screw holes for the extension leaf, glue one of the drawer pulls back together and affix to the drawer, straighten the hinges on the one cabinet door and reinstall the door.)
The machine needed work too. It was the most freely turning thrift store machine I've bought, and would spin a couple of revolutions before stopping if you just gave it a spin with your hand, but it needed the light and motor rewired and I didn't love that the original wiring (pedal built into the side of the drawer banks with the controller mounted under the drawers) was wired to the machine, and not to the plug, so I changed that too. This way it's easier to service the machine. I can just take it out and put it on the bench, instead of having to pull the wiring block apart, or leaving the motor and the light with the cabinet.
I serviced the machine on Friday and today it's going to get its test sew. Based on the amount of work I did on the machine, what I paid was likely "fair".
I mention all of this because this is very likely the same amount of work you could be looking at for a similar machine. All in all, I probably have 5 hours into the machine and cabinet and it still hasn't sewn a stitch for me.
All for a machine that you would have a hard time turning around for $100 in my market despite its extremely clean, fully serviced and perfect wiring status.
There's a similar machine, identical cabinet and similar shape to this machine's original state in our buy and sell at the moment for $40 and it's been there for more than a week at that price.
