As a "short (mid) arm" machine quilter, it would be worthwhile to
rent a UHaul and get the Kenquilt at $1500 as a starter machine.
You can then decide after doing lots of projects on this type,
if you want to invest in a Long Arm. It will at least help you develop
initial skills of loading quilts, buying supplies, adjusting tensions,
and solving other minor problems... plus finding out if there is a
market in your area to warrant a Long Arm .
