It would be great if you could ride one before you buy.
My husband has a couple of them, and he LOVES them, as many people do. I have one of the original frame NWTs (from 1994 I think), and it is about 29 lbs the way I have it set up with the rack. Now, I hate to ride it, but I ride it all the time because it fits in the back of my mini-cooper. It rides very smoothly with the harder tires, and of course the components are as good as any, as the price reflects. I have never, ever, been happy with the twitchyness, and 'ride-feel' of the bike. Other people say it doesn't matter, and I can't define 'twitchyness', it means something different to everyone.
Call BF and ask if there is someone in your area that has one to test ride (I think they still have that program). It's alot of money to spend for a bike like that, and find you don't like it. My experience may be different, because my husband's bikes have a longer wheelbase, and I'm OK riding those.
