Price advice on some secondhand Takumar lenses?

I know TurboFrog has the magnificent Super Takumar 50/1.4, sooo...

I'm looking at buying the Super Takumar 50/1.4 together with the Super Takumar 100/4 Macro for a total price of €180 (about $240). Is this a good deal? I'll probably try and underbid to about €150, but if even that is a bad price I might skimp out of the deal entirely.
