Yeah, I just buy Corps or Chap Mei vehicles and repaint them. You don't have to repaint the Corps APC, it comes in Tan/Flat Olive. I also do minor mods and repaints of Joe Vehicles. The Bridgelayer looks Russian and the Equalizer looks like a ZSU-24-3. I even repainted the GI Joe Ghost-Striker to be a MIG!
And Smalljoes has MIG 15's in 1:18....

I still wish I could get my hands on a T-80 ot T-72. Seems all the 1:18 scale russian stuff is Korean War or WWII vintage!
