I looked at these as a possible option in my quest for a longarm I could actually afford.
The 201 sewing machine was an absolutely great one. But, it isn't the best one for free-motion quilting.
It has a smallish class 66 bobbin, which means that you're going to be changing bobbins almost twice as often as with a machine that takes a class 15 bobbin.
The horizontal bobbin can cause more skipped stitches than most vertical bobbin machines.
The horizontal bobbin cannot be accessed from the underside of the machine, which means that you will have to move your machine out from under the quilt to change the bobbin.
I've always wondered why they didn't build this machine on a model 15. I probably would have bought one a long time ago if they had.
I would even like a stretched sit-down version of the 15.
When the bobbin runs out, you can reach in and remove the bobbin case from under the table, change bobbins and replace the case very easily - you're back to sewing in less than a minute, right where you left off and without having to remove the quilt.
