Yes, the Panther is my favorite as well.
Considering what is shown is a one of kind model, you'll be happy with Tamiya's recent preview of their pending 1/16 RC Panther G or Wecohe's $$$ conversion kit using existing Tamiya running gear. Rumor has it that Trumpeter / WSN will be releasing a lower cost Panther as well in the coming year. And with these kits coming on line, it will only be time before Elite Armor or Imperial release a Jagdpanther conversion kit. At long last there will be Panthers available for us common folk!
Here is Wecohe's page along with several photos of their new conversion kit:
