Beyer and Lekebusch were where I started with techno as well and in fact the Swechno sound represents most of my vinyl collection (as I haven't been collecting new records for about two years now). I had the great pleasure of seeing Lekebusch live last October and he was fantastic, really lovely pumping sound and kept me on my feet all night.
Stil the new stuff their are mixing out doesn't compare to their old stuff, I've got some Beyer sets from 99/00 and they are some of the tightest mixes I've heard, the records all gem together nicely, mixing is smooth and there is a lovely progression of sound, atmosphere and pace throughout a set.
