At the end of July I'm visiting Berlin with some friends for some goold old partying (& to check out the city). Me and one mate want to spend one day digging during the trip. I was wondering if somebody has a recommendation for a second hand record store with electronic music? Preferably minimal/(tech)-house/ techno but I'm open for other (electronic) stuff too. I've been to Audio-in before which was nice but I would like to check out something else. At HHV, Spacehall and Hardwax ordering online is also possible so I don't really feel the urge to digging there.
From what I've heard, the Record Loft is supposed to be a good place for second-hand digging. Can any of the Berliners (or people that have visited) share their experience? Or recommend another store ofcourse.

Thanks in advance!
Marty
