I have bought a refurbished brother from overstock(xl3500-i which is mechanical) and new one from walmart(SQ-9050 computerized) highly recommend both spent 109 on the first and 200 on the second which has more features. The first I have had for about 6 years and the second for a year, neither have had problems and I think I have only serviced the first one for a cleaning once. I did have to return my first refurbished one as it wouldn't start but they sent me a new one super fast and it has never been a problem. Overstock has great customer service
