I have a feearm Supermatic, the beige and tan version, which I think was the last of the Supermatics (maybe the white one was the last?). I have seen flatbed version of the twotone beige/tan, as well as the white version. I think they were called "Supermatic Plana" or something like that. The tension should be easy to adjust, there's even numbered settings for bobbin tension and rather accuratey too. Tension can have something to do with cleaning and threading, and I know you have to make a point of getting the bobbin thread fully into the tension spring by pulling the thread down behind the bobbin case. It's easy when you know it, but a common issue with these models. I know two people who use their freearm Supermatic regularly even for quilting, even as their go to machine. A flatbed version in a cabinet should be luxury. There are a few here on the forum using Necchi Supernovas too, so it's well withing doable.
