couple of questions...
How hilly is your area?
Do you want drops or some sort of moustache/north road bars?
STI/ergos or barcons or downtube shifters?
friction or indexed?
I have a stock one but replaced the following:
vo porteur bar/stem
tektro silver cr720
suntour friction levers mounted to some shimano barcon pods
brooks b17
will probably get some paselas or marathons, hammered fenders, front/rear rack of some sort
my 2nd is a hodge-podge of parts:
tektro cr720/oryx with koolstop salmons
ultegra crank with 39t/bashguard
stock salsa bar/stem/seatpost
old tiagra rear derailleur
campy ergo 9 speed
ugly front cantilever mount rack and wald basket zip tied to it
