The singer had some electrical issues and seemed a little sluggish, so I opted to leave that one at the store. The Necchi, that I wasn't really interested in was like a work horse. It was quiet, smooth, kinda like driving a luxury car, so I brought that one home. All that to get to the question: I want to get some cams for it, I've looked on E-Bay the sellers for the ones listed don't know which machine they are for. Are the cams for the Necchi interchangeable or are the specific to each model? I'd appreciate any information. Thanks in advance.
