Second Sugino. That was my first thought when I saw this thread. Find a Sugino crankset that matches your chain and cassette. You may have to go to a bike shop and have them look, but Sugino makes a great selection of options, BCDs, crank lengths, etc. Good quality stuff. You will be able to get rings for years. I'll bet you can do almost anything you could possibly want with a 110/74 BCD crankset. That standard hads been around for 40 or more years and isn't going away. Sugino will keep making those parts for the very solid business they do with bike manufacturers. I've run 52-42-28 Sugino for decades on various bikes. Since it is 110 BCD, that 52 and 42 can go much smaller. I use a 24 inner on one bike (SunTour, not Sugino but same bolt pattern).

The Suginos work well with Shimano sealed BBs. (I've heard the tapers are a little different and one shop will not sell me a Shimano BB to go with my track quality Sugino 75 cranks, only a Miche BB but I have been mixing the lesser Suginos and Shimano BBs for years with no ill effects.)
