While Shimano makes good chains, I would look for a chain that has a "quick link", "power link", etc. When removing a Shimano chain it requires a new pin, at $2.50 each, on reassembly. I take my chains apart for cleaning, and Sram Power Links make chain removal and reinstallation easy. I've used Sram 951, 971, and 991 chains and they are all good.
