I'm pretty much the same way with chains & sprockets. I order a lot of stuff from Bike Bandit from time to time, and just get whatever steel sprockets and o-ring chain they have listed for my application in their 'Aftermarket Parts' section. Most recently I think I wound up with SunStar sprockets and a Moose o-ring chain with master-link.
Nearly all of my riding (seriously, nearly 100%) is singletrack trails in 3rd gear or less, so a chain & sprocket set will last me a good long time. I hose the mud and sand off, and lube with chainsaw bar oil after every ride.
