What is the most you have ever spent on a comic?

a) Probably a Cerebus phonebook for £15 or so.
b) The giant Crumb coffee table art book for about £20. In terms of single issues I remember spending about a tenner for an old MY GREATEST ADVENTURE with an early Doom Patrol yarn in, for a birthday present.

a) Probably one of the Bizarro hardbacks, £25 I guess?
b) I bought the Elseworlds 80 page giant a couple of years ago for (I think) £35. It's the only comic I own as "an investment" - it's gone for as much as £80 in the past on ebay.

New: $20 for the Camelot 3000 graphic novel
Used: 15$ for a Mutant Massacre issue; don't remember which one

(It was probably the Thor issue, eek)

$40 on the 1st printing of the OOP and HC Elektra Lives Again. Of course it's now back in print.

NEW: I just dropped $25 on Epileptic (worth every penny!) & The Originals (ditto!, tho on a smaller scale); as for a comic comic, I think the most I've paid for a single issue is w/ The New Frontier (TOTALLY WORTH IT). I'm gonna probably drop the cash ($50) for that super-snazzy Watchmen HC coming out soon, though, as my TPB copy is a) ratty and b) AWOL.

USED: I'm thinking $30-35 for an issue from the Claremont / Byrne X-Men run (I think #139 - the one w/ WELCOME TO THE X-MEN, KITTY PRYDE ... HOPE YOU SURVIVE THE EXPERIENCE! on the cover, though it might've been the 1st part of the Days of Future Past story); I also might've dropped $30-35 on Spider-Man #238 (1st Hobgoblin) (w/ tattoos), back when I was a cough "serious collector".

FYI, that issue of ASM replaced the rolled-up non-tattoo'd well-read ratty copy I bought @ the local drugstore.

I've never paid too much for a comic except for list price on big trades. The Prisoner miniseries was a little above cover price, I think.

I have wondered many times how much they're selling the Lois Lane issue they have at the comic book store for (it's not Black Lois, unfortunately).

I think I paid $45 Cdn for the Crisis on Infinite Earths trade. Most trades are between $20-30 Cdn, which is a little high, but not completely obscene.
I remember buying the Watchmen trade in 19990 for $20 and feeling like I needed an armed escort to be carrying around something worth so much. (I also had a Watchmen watch!)

a) The English translation of Tintin in the Soviets, a "special" "limited" "edition" that was only on sale at a museum exhibit. About 25 quid. I was 10.

b) My favourite ever purchase: JLA 21 -- "Crisis on Earth-One!" -- from teen-nerd-paradise Stateside Comics in New Barnet. About £35. I was 11. Comic itself a bit rub.

Can we add a "Best Bargain" category here? In which case:

c) Doom Patrol 19-33, from a comic mart near the British Museum, for £8! Oh, the old days.

I forgot, when you are 11, £35 = FORTUNE.

a) Whatever list price was for Comix 2000 (the 2000-page hardcover).

b) $20 for X-Men #137, back in the day--I'd started reading with #138, and realized after a few months that I was hooked...

a) probably either the Cages hardcover from KSP or the From Hell signed limited hardcover from Graphitti, they might have been over a hundred bucks. lots of new comics cost around A$70-80 these days though (esp. from comic shop vs bookshop)
b) either the never-reprinted first Alan Moore issue of Saga Of The Swamp Thing (#21) or some special Cerebus (maybe the Jam or the gold-logo #0) or a single-digit Flaming Carrot, I might have gone over $20 for any of those

Oh yeah, Cages. $50.

d'oh #20 for that first Moore Swamp Thing, #21's the one that ALWAYS gets reprinted

I think I paid about £7.50 for Avengers #37.

a) Not sure exactly, but definitely no more than $20, for a bound volume or graphic novel. My wife paid $40-ish for the Locas she gave me for Christmas.

b) surprisingly little, probably no more than $5 or 6. The valuable back issues I have were traded for -- I traded a longbox of "meh" for FF #48-50, the Death of Captain Marvel book and a handful of early Cerebus issues in Memphis in '83. Lucky Fights It Through I found for a buck at an antiques shop in Tupelo in '90.
