110-74 crank and replacement rings

Keep your crank and don't worry about the 110-74 bcd crank standard as it is alive and well and not about to be discontinued. The problem is really with local bike shops that are pressured by Shimano marketing practices and pricing incentives to stock Shimano components.
Both TA and Sugino continue to manufacture 110-74 bcd cranks and rings and continue to come out with new crank models. Sugino rings are about the same quality, maybe a little better than Shimano (which doesn't say much) whereas TA rings are the best wearing rings you can find. Don't worry about the TA prices as $/mileage is unmatched. If you're on a tight budget, go with the Sugino rings. If you need to order rings, I have used two reliable TA ring sources - Peter White Cycles (Hillsborough, NH) for TA rings and Harris Cyclery (West Newton, MA) for TA or Sugino rings. They both have websites and if you call they will provide all the information you need.
BTW, if your thinking or replacing your tandem cranks you might consider a Zephyr tandem set from Peter White.
Regarding the post about spacing problems with mixing ring manufacturers this is never a good idea. However, the TA and Sugino rings can be mixed but you would be sacrificing mileage with the lower cost Sugino rings.
