The Tokarev is the classic, but beware of different countries of origin-- price wise it looks like yours probably is a Romanian. They make pretty fair weapons, but I have seen Romanian import Tokarevs be butchered with a safety, and sort of "rattley" when handled.
The CZ52 though is made well-- the only drawbacks are the firing pin and weak springs. You can pick up both of those fairly on the cheap.
Both are fun and the 7.62X25 is a hot little booger of a round-- just make sure that is you shoot the corrosive stuff you douse the innards down with windex or diluted ammonia when you are done... then lube it up--
Good luck, and at those prices, you can't go wrong with either.
