Nobody can make the decision for you, but I will say that I'm very, very happy with my K1000. It has impressed me beyond my expectations.
It has become and will remain my main heaphone.
Unlike some I also find it quite comfortable.
I prefer it to the better stats I've heard (007 Mk1, Lambda, Lambda Pro, Sigma Pro, HE60 & ESP950), but that's just me. I've never been as fully impressed with stats as others have.
