Check out the Homesteader at
http://www.thequiltingsolution.com/ I have one of their older machines and I have received great customer service, prompt and easy to deal with. I managed to get mine second hand, but most everybody that gets one doesn't sell it or trades it in for a newer one. I think in the last 5 years I have seen a total of 5 on the different forums for sale. That sold me more than the other people raving about the machine.
Good luck on your search!
