I've been playing PF1e since it came out and been slowly collecting all of the setting-neutral rule books. The only one I'm missing now is Book of the Damned, which is absurdly expensive now that it's out-of-print. I was lucky to grab a Like-New copy of the Advanced Class guide on eBay, but that was only after hunting for months. If Paizo would make all the rule books PoD, that would be great.
