Well my vote went to the $250-$500 range which was my answer to the question "At what price will you automatically buy a new comic cover". Plus I can't really afford anything much more than that so my cover purchases are obviously few and far between
Thankfully, at least one of my fave artists and good friend, Stuart Immonen gives me a much appreciated "family discount" on his artwork and I pick up occasional pieces like the recent Patsy Walker: Hellcat cover. Note: If interested, Stuart sells his work through Fanfare.
Tom at Fanfare sells Stuart's Ultimate X-Men, Ultimate Spider-Man, Ultimate FF and Hellcat covers for $600-$1000 (most of them being closer to the $750 mark) which I feel are reasonably priced in comparison to other cover pricing which I couldn't even consider.
You can see the Stuart's Fanfare pages here -
