To me it looks like a good lower cost alternative for a quilting system. Since the 201 is a very reliable and easy to maintain machine, if a person doesn't need fancy stuff like stitch regulators, etc., I think it's a very good deal. The prices are good.
I have a BabyLock Quilters Choice Professional short arm on a frame. The bobbin is loaded from the needle end of the machine, underneath. I still have to move the machine out from under the quilt to replace the bobbin. There is no other way to do it, because of the rolls of the quilt parts in front blocking access to the front of the machine. So I don't see how a drop in bobbin would be an advantage...you have to move the machine aside no matter what.
