You're probably looking for something along the lines of plain C&V style chainrings, but I used a modern ramped-and-pinned 50T Shimano ring a few years ago and was pleased at the shifting. The 4503 model seems to be gone, but you can still get:
5703: https://www.amazon.com/SHIMANO-FC-57...00553OYFE?th=1
3503: https://www.amazon.com/Shimano-130mm.../dp/B00N6KHI56

I have a couple of lightly-used plain Sugino 48T and 50T rings, but checking back, I paid $30-40 for those, so I'm not sure if I'm ready to let them go for much less than that, yet.
