I've never been a whale and likely never will. I did smell something in the air late last year and got serious about acquiring a copy of X-Men #1 for my run, and I'm really glad I did. I picked up a few of the other bigger silver age keys I needed for the run, but prices have finally gotten to where I had to stop. I'll keep working on the filler issues, no one is buying those.
And I'll keep working on all the other runs I chip away at: Tales to Astonish, Amazing Adventures, Incredible Hulk, Tomb of Dracula, Marvel and D.C. horror, etc. etc. Plenty of stuff out there that's super affordable, and probably will always be.
If the market does bust, or if there is a serious correction, maybe I'd be back in to track down one or two more of the bigger books I'd like to have like Hulk #1 and ASM #1, but for now and the foreseeable future no way, Jose. It's high grade copies of Marvel Premiere, Creatures on the Loose, House of Mystery, and Uncanny Tales from the Grave for me.
