Re: Wtf mf!?
I think the first act boss that can drop all jewelry is Hell Duriel, but Hell Meph is usually the one you run since he's so much easier (and if you've got a build that can do the moat trick, it's cake).
And let me say, 150 runs is... to be nice, not enough. 1,000 runs is better to show some good variety, but even that isn't close to a high amount. That means, don't expect to be overloaded with EUs, rainbow facets, Azurewraiths and Stormlashes; it takes a lot of time and effort regardless of how much MF you've stacked on. Meph's a good place to start, but you also shouldn't stay at Meph forever since he can't drop everything. Baal runs are fine plus you get good experience on /p8, Pindle's good over LOTS of runs but can't drop six (eight including torches) items, as are alvl85 areas where you can get some good socketed stuff.
Oh, and barbs are best for either Pindle or alvl85 areas for their item find ability. Act bosses... without a killer weapon, not so much.
