The PP is still relatively plentiful, and at far less cost than a PPK.
The Manurhin manufactured/marked post war guns are the best value by far, and typically have better bluing than the Walther marked and finished Manurhin manufactured ones do.
Yes Manurhin of France made all the PPs and PPKs for many years after WW2. The ones you see with Walther roll marks were made in France, then the parts were shipped to Ulm for finishing there.
Simpsons has several pages of Manurhin PPs in .22, 380, and 32acp, just as a way to judge the market.
The PP is larger than the PPK, but it's still not a big hand gun by any measure, and the .32s are the most fun to shoot.
And one of the best things about them all is that they are representative of the old world way of making hand guns.
Hand fitted by craftsmen, they are just beautiful things to behold.
