All P08's equal in workmanship?

[Uechi]

I am assuming that all Lugers/P08's are not equal in quality/workmanship depending on when they were made and what factory made them. Am I correct? If I am, how would you rank the manufacturers? Getting ready to buy my first P08/Luger and I'm trying to figure out what to buy. Pricing is important but not nearly as the workmanship aspect and condition.
