David,

The Pz3 comes with a metal gear box, if i'm reading it right. What's to upgrade? Am I missing something? The only thing I might want in the future would be the metal drive wheels and tracks. Do you know if they are available? $69 seems like to good a deal to pass up. I looked at the KV-1 but I'm more into German tanks than Russian. Is the KV-1 much bigger than the Pz3?
