I do pretty much the same as blatz - I serve right from the same keg used for lagering. I cut the dip tube in one of my kegs a while back to do the double-transfer thing, but have since fount that unnecessary unless I'm going to travel with the serving keg. As others have said, as long as the keg remains still once it is on tap, there's usually only a pint or two of cloudy beer and the rest of the keg pours crystal clear after that.
