I have several that are in cabinets. Only one can change out from one machine to another. The problem with all cabineted machines is the space they take up. I was just looking at 2 different cabineted machines one that is interchangeable and one that is not. I wanted to switch their locations for the smaller cabinet to be in my sewing room where I can put a different machine in it to make my sewing room look a bit neater. It comes down to the space each one takes. This is just something to consider. I love the way they all look. As far as were to look for one I would start of Craigslist only because I am one of these people that look for a bargain anywhere I can find one before I go to a retail store of any kind. I would also look in resale shops. I don't mind refinishing a nice piece of furniture to get it to look the way I want.
