Aww, that sucks. Wished you would have kept them.
I really enjoyed his early works. Sure he started out a little shaky in terms of characterization, but very quickly Nick seemed to've done his homework on the characters of DL, and very shortly his portrayal of the companions was pretty spot-on.
And he always gave us a harsh post-holocaust scenario. Titles such as Nick's Zero City. Savage Armada, , Devil Riders and Bloodfire, just to name a few, were excellent entries in the DL universe.
