Sheepherder, I already have a very nice matching AE that I bought years ago. So, for a shooter, I bought one of the East German VoPo Lugers and had a 6" .30 caliber barrel installed. Not too long ago I had G.T. install a 4" 9mm barrel on a WW1 Artillery receiver that someone had chopped the barrel off just in front of the rear sight mount. Now I have a shooter that I can swap uppers on and use either .30 caliber or 9mm as I please.
The AE is first and the converted VoPo with the 6" barrel is second. The shooter with both uppers cost me far less than $800 total.
