TM,
I have the panzerjarger from "Ironside" and believe it or not it is the Italeri kit (PZ I - most of the same sprues as PZ Ib as well) ) w/ a fret of PE and a resin conversion from ADV to make an open fighting compartment. I could literally build the PZ I fom this.
Anyway, I've built the PZ Ib ( command tank ) from Italeri - and was a nice little build. Nice detail, crisp molding, and not very much usual Italeri problems.
Then as far as Dragon, with their relationship w/ Italeri, they always seem to take Italeri kits and go up a couple notches.
