if you want the bike, and it calls to you, you should probably just save and get it. that being said, its really just gimmicky to think that a belt drive will have a lot less maint. than a single speed/fixed gear bike, it takes about 30 seconds to lube a chain every few hundred miles, that amounts to a few minutes over the bikes lifetime.

also, if you really want a bad weather bike, and a "training" bike, i would think a SS cyclocross bike better suits your needs. caliper brakes are really a show stopper when it gets really nasty out, and the ability to run knobby tires when its snows, etc will be handy. you also expressed an interest in riding fixed, i wouldnt buy a bike that precludes this possibility, if you think it may be interesting to you in the future.

just my 2 cents though.
