Personally for me, yes some are in ranges I am comfortable with, but granted I am not chasing the big keys at the moment(aside from Showcase 4). I needed to upgrade my Conan 1 and figured a 37% price cut was good enough for me. If certain books keep dropping and I like them I average down and buy another copy or two. When I go to sell to shift funds in another book, those copies have always had good returns over the years.
To avoid boring you all, I deleted my full paragraph on the stock market and comics.
