If you are that new to quilting, I would definitely wait on a long arm. This may be a hobby that you stick with and go full steam ahead. May also be a hobby that you enjoy on a slower path. Always the possibility that it dies after a short time. A long arm is a big expense if the desire dies off. In the meantime you can quilt and practice your skills while you decided how deep you want to get. Also gives you time to test some machines at a quilt show.
