I've had years of good service with fkktour.com in fact I started with a personal guide (German guy) who met me when I got off the plane, took me to 2 clubs and then returned me to the hotel. One of the X guides now runs the biggest German discussion forum, which tells you a bit how well versed they are.

I suggest you ask others who have ACTUALLY used the service. Sort of like asking someone about a club who has never been, makes more sense to get actual experience.
