I have both an RCBS and a Lee 20 pound pot. The Lee gets the bulk of the work; doesn't leak as much as some would lead you to believe. On the few occasions it starts to drip, a simple couple of twists with a screwdriver on the valve seat rod stops it. Some people put a weight of some kind on the handle to keep drips from happening. I keep a 3" metal screw-on jar cap under the spout and it catches any drips that do happen; then just use a pliers to pick it up and dump back in the pot.
