Are you suggesting it brings you anxiety to spend that much on a book like that? Then don't!!
I know I don't. I'm still cheap, and it brings peace of mind. I shoulda/coulda bought all those same books at prices reflected in even earlier guides, but in the end I'm happy with what I DID get. Sure, I'll never own a ton of books that have exploded in price, but there are thrills aplenty to be had in the $5 to $20 range still. Is Haunted Thrills a killer title? Darn straight it is. Would I hate myself in the morning if I paid $500 to a $1,000 or more per issue? Absolutely.
At some level, it stops being fun. At least for me it does. When you were a kid, you could save up your allowance (if you got one!) or your grass-cutting or birthday money and score a mini-grail if you sacrificed long enough. Now what are we supposed to do? Forego buying a new car for a decade or so?
I don't know how the Geffens and the Cohens of the world sleep at night: do they ever stop and say "holy cr@p, I just spent a fifty million on a painting?"
