The later issues really are neat, and you know how much fun the pre-heroes are!
I'm on too tight a budget to ever run with the high grade pack. I'd have to give up some cherished books to swing it, or stockpile money for months. (It's no fun to go a year without buying something. Also, I'm afraid I'd convince myself that the money would be better spent elsewhere) So what's left for me at this point is under $100 comics. No problem! I still need tons of pre-hero Marvels, not to mention the Lee/Kirby westerns I don't even know about yet!
Now that I think on it, once a Marvel guy completes his hero runs, where else is he going to go? Even the highest of rollers would be tempted if a beautiful, CGC run of pre-hero Strange Tales were to present themselves, wouldn't he?
