How about that bunch of low cost highly effective WWII SMGs: The Soviet PPSh-41 and the Brit STEN gun ?

In the WWII era, I would definately vote for the PPSh-41. I have had the good fortune to either own or fire most of the major automatic weapons of WWII and was really impressed with the Rusky piece - not only with the reliability, but also the high velocity Tokarev/Mauser cartridge. Also high on my personal list would be, suprisingly, the Beretta 38/42.
