I have owned a couple of used BF NWT and several Dahons. The BF were made very nice and I liked the idea of made in the USA. I didnt care for the fold of the BF and they didnt ride as nice as I thought they should. I have owned sevearl Dahons Piccolo, Curve SL, D7,Boardwalk.... They had an easy fold but I didnt care for the gearing or the 16" wheels were too small for me. I just picked up a used 2007 MuSl recently and it rode like it was made for me. The MuSl is a keeper for the type of riding I do. If a used Brompton or Tikit comes along I would like to pick up one of those also and see what they ride like and see if they would become a keeper also. Get what fits you best and what you can afford. These bikes dont break down that often so I wouldnt worry about parts until you needed them. When you do need parts then get some help here from the forum on who can help you out.
