Mark III Red Stripe if you can find one will nail Justice and Puppets, with a few pedals and some minor adjustment you can get the Load and Reload tones as well. As far as clean goes Roland JC-120 will give the classic metallica cleans like ONE and Sanatarium. However a Fender Deluxe Reverb will get you all the other cleans pretty damn spot on. Run into a guitar with EMG's of course and Avoice the roadster it will not get you metallica tones that you want.
If you can't land the above nothing else will do other then the Mark V.
Do not get a VH4, like mentioned it does not get you the tone you want alone and Hetfield blends it with his rig. Plus his tone has suffered since adding it in my opinion.
