PU sniper scope

Where is the best place to get a PU sniper scope? i want a great scope but i dont want to get ripped off eigther. i would like an original most of all. who sales original PU sniper scopes? who sales the best repo? i found the one made in st peterseburg that looks like its the best quality but i am not sure. i know very little about sninper scopes etc so any help is needed. it will be going on a ww2 Ex-sniper so i will need a base, mounting hardware, etc to.

thanks -Joe
