I am aware of a few options for a 5 hole 110 BCD 165 crank for outboard BB.
COBB compact, there are some on Ebay currently. Look at the one from Bikewagon on Ebay for $208
Shimano 105 FC-5750 compact. Discontinued but there are some used ones on Ebay(possibly out of country) and I think some new as well.
Sugino XO compact. These are available directly from Sugino with some interesting gearing combinations but they aren't cheap.
