I personally don't like the looks of the S&W PPK frame. The extension of the tang (beaver tail) ruins the looks of the gun IMHO. I would look for an older Interarms gun.
Like you as a kid, I was drawn to them by the James Bond mystique. I currently have a stainless PPK .380 (Interarms), a PPK/s .380, and a Manurhin PP .32, they are all fun to shoot.
