i cant think of any brands besides that one... but what i've heard about them is all good things! may i suggest going with a aluminum shaft... they make a carbonfiber shaft as well, that may offer better performance over the aluminum one, but the carbon shaft will snap, whereas an aluminum shafts tends to bend... now the fact possibility of that actually happening is slim-to-none, but believe it or not, this actually happened to a friend of mine... so imo, go with the aluminum shaft, it only weighs a few more ounces than the cfiber, and is less expensive, and the performance is pretty much the same for both of them (since the drive shaft is more for weight reduction, not raw HP or torque gains) but take a look at all your possibilities and make a decision based on what you think is right for you. hope this helped you out a little...
