That style of CP is fine, so long as it's just a left-right joystick and one button. That style of cab is awesome in my opinion, but I do prefer a CP that has the joy pointing up, like most uprights. Since DK is 4 way, it might be better to let a collector snap it up.
After having said that, if I saw that cab for $450 here in Australia, I'd still probably snap it up...
