Dark Horse is fine (for the most part, although don't get me started on the exclusion of Conan covers in the Chronicles series...). Publishers pretty much know that the faithful are going to plop down their cash for these collection series no matter what, so if they want to change the dustjacket or cover, they probably feel free to do so. The annoyance is just part of the price you pay for being a comic lover (aka OCD perfectionist!)

"The best place to start an adventure is with a quiet, perfect life...and someone who realizes that it can't possibly be enough." - Kevin J. Anderson
