Personally I’d avoid a folding bike if you’re going to be doing serious miles on it there are just too many things that could go wrong.
Ben that used to post here once upon a time does S&S couplings if that helps; kinetics
I do like the Tranny, but you’re right, it isn’t cheap and I was told recently it’s very harsh ride.
freeload[/url] racks mean you don’t have to worry about a frame having mounts – they have at least one mail order dealer in Germany so you don’t have to get them from NZ.
Personally, I’d go for steel/ally mtb in a bag or if you have the time/money/inclination get s&s couplings put in (i think it has to be steel for these) to make it more packable and manageable. But do consider how much of a pain it will be dragging a bike in a bag around when you are not riding it and how small you can make teh bike bag when you are riding.
sorry about the epic post; bored at work!
