My only contact with the Truman Deathlok was the introduction of it in the X-Men crossover, which I found very weak (having been such a huge Michael Collins fan, I might have been biased). What is it that you guys think so great about him? What made that version stand out from the previous? I've been thinking about purchasing the TPB, but it's kind of expensive.
As for the great run of artists, after Cowan and Manely left, no big names took over for them.
