Looking for good deals can be a part of the fun, but not when you actually need something quickly. I'm lucky to have a good boneyard near where I live, and found another in ABQ where I am working for a few. We're a bit spoiled in the Southwest since are chrome bits don't rust like they do elsewhere.
I've also found that quite a few Ebay sellers put stuff up for ridiculously high prices hoping to land a whale, but going through the "sold listings" gives a better idea of what stuff actually does sell for.
Regardless, good luck! If I was back in PHX I could look for stuff you need, but it'll be a few weeks before I return. That being said, I've also picked the 400Fs and 350Fs pretty clean outta the yard...
