I just recently purchased a "new to me" long arm. I would say this...if you are really comfortable and feel like you are or can with practice get good at quilting on a domestic...a large throat sit down might be a good option for you. I love my long arm, but the only reason I bought such a monster was because I had plans to go into business with it. I would say identify what you WANT and what you NEED and then go from there. Go test everything and try your best to be realistic about what you'll really do with it. Good luck!
