Sorry, your title reminds me of my old high school football cheer (reworded a bit):
Mid arm, long arm, how's it built?
stand up, sit down, quilt, quilt, quilt!
But seriously, I did find the FMQ movement on my domestic machine much more difficult than using a longarm. For me it was much more natural to move the pencil rather than the paper. It sounds like the opposite may be true for you. Another thing you may think about trying is to see if there is a place near you that rents time on a long arm. This may help you cross that off your list.
