Hello all, I am looking for a compact crankset with preferably the following attributes:

170mm arms
50-36 chainrings (or just a 36T single chainring)
decent quality & condition, but not expensive
outboard bearing (the kind with cups, e.g. FSA mega exo)

all of this is what i would like ideally, but i'm open to other stuff too. let me know what you got via PM or post here.. thanks!
