Some people may say this is a silly suggestion; I've got about 20hrs in the real aircraft, but I back that up with practice on Microsoft Flight Simulator, which is practically free. It's not nearly as realistic as the PNPT II but with a world wide database of VOR/ILS/NDB and everything else it's actually very useful. I don't have an instructor with me on the computer, but sometimes I prefer to practice on my own. As far as training that is logged is concerned IMHO nothing beats the real thing and as long as you learn in plane you already know well you shouldn't have too much trouble keeping up.
