I'm getting rid of my two PPK-20s; I acquired the second one to salvage parts as I couldn't find them individually...
Both replicas are in perfect working order. Only the small tabs (see photos 4 and 5) that hold the stock in the extended position are broken. If you're handy, a small hole in the stock with a screw and nut will fix them.
The one at the top in the photo is completely original; the second one has a Gates Aster V3 SE Expert motor. Both have the original high-torque motor. Magazines can be switched to 30-round or 80-round capacity.
