At $250-$270, I think the new 1/16 Trumpeter Panzer IV H/J kit could be used as an update/detail set to make the HL or Tamiya Panzer IV's look better. It has 6 sheets PE and the plastic detail of the kit is better. Check out this link to the Trumpeter site that shows all the sprues and the PE detail.
