Should I get a Rohloff Speedhub?

I'm considering getting one of those 14-speed internally geared
Rohloff hubs, either for my current bike, or -- preferably -- for a
new rig (road sport/touring bike). Anyone know how well they hold up
over the years? (I'm
getting sick and tired of chains falling off after a shift at the most
inoppertune moments (ie., steep hill) , not
shifting right, etc . . . and I'm still using 8 & 9 speeds . . . I
pray to God I never get stuck having to use that 10 & 11(!!!!) speed
crap!) Actually, what I'd REALLY like to do is pair it with one of
those SPOTS bikes/carbon belt drive system, though I'm not sure how
compatible the 2 are . . . anyone know? Is there a dealer who sells
a
complete bike with the Rohloff? (I'd prefer a TI frame.) Are there
any single speed/track frames with 135mm
spacing? Any "horror stories" with the hubs? (My only fear would be
trashing the rear wheel while on tour . . . its not like you can find
a shop and pick up any Shimano wheel, and off you go . . .)
