nice, that you try talking to us in our native language, but don't bother and just go for english. even though our english sometimes isn't better than your german
all right, berlin has plenty of good artists. i might not be the best one to recommend you a studio in berlin, since i haven't been there before, but i know for a fact, that some other users can list lots of their favorite berlin artists. but on the other hand, if you already consider a ~80mile drive, you can also try to get an appointment by a member of this board.
tattoogermane is doing really kickass work! and you might end up getting a really nice memory done by him. he has a shop in hohenwarsleben (suburb of magdebug), this is ~50 miles away from dessau and it's much more comfortable heading into his direction rather than getting lost in the middle of berlin =) without a clue where you are.
but i have no idea if he has some time to throw the piece onto your body? he might have a tight schedule... i don't know, but he's i a frequent user in this forum and it's smarter to talk to him directly.
so long,
holisch
