YW. It's worth noting, too, that you can't expect to find them in Normal or NM, of course. Two of my three HRs were found in level 85 areas, and the Zod was dropped by Diablo himself (non-quest), the Lo in the WSK, and the Ohm was dropped in Hell cows. I was playing a sorc for tons of runs and a Zealot pally for Ubers and Nilly runs and the occasional Clone appearance. I played a lot, getting my sorc to level 93 without ever joining a Baal run.
