If you are willing to tolerate 4 bolt patterns, and especially asymm 4 bolt, you should have plenty of options.

I being retro style, I wanted a 5 bolt spider on a standard BCD.

You may also want to check Litepro, a lot of folks use their stuff, however some of it looks just a little bit too light for me on the rings. But if you need to swap the ring anyway, you might be able to find the right crank only in Litepro, then buy standard rings for it.

My town has one of the best bike shops in the country for their supply bins of used parts, and I might have gone that route, but the Prowheel crank complete with rings and bearings, was cheaper than same in good shape at the bike shop.
