Where in Germany? My company pays around 80k total for lead/principal roles with your experience, in Berlin. And I'm sure you can make quite a bit more in Munich, Stuttgart, Frankfurt, ...

Also, keep in mind, while $250k in the Bay area is indeed more than nice, there are quite a few people making half of that if you don't count the monopoly money in their total comp. In many ways you live a better life with 60k in Germany than with 120k there.
