I've heard of people that have had problems with Litespeed's integrated headsets. The problems come in when the bearings aren't parallel to one another; it causes the bearings to be either too tight or sloppy. Fortunately, Litespeed's intergated frames use a pressed-in race that the bearings ride on so the frames are repairable. Unfortunately, the frame must be sent back to Litespeed for the repair.

I wouldn't be concern buying a new integrated headset Litespeed, but I'd be careful purchasing one without a warranty.
