I guess I'm one of the lucky ones. The SR is still running the original cork taps and they work great. I did find out the hard way that draining the tank and leaving it sit is not good for cork taps! They dried out and ruined one of them. I replaced the cork about 8 years and it's still working fine. I just leave the tank full.
The RR is running an Indian made tank. It had a different thread pattern and I had to run generic lever taps. They work well, but I really wanted to put a set of cork taps on it.
