I've got SMC's kit...he is a great guy with a good business. Tends to replace pumps if they get shot and keeps you notified. I've used denatured alki and meth both with a little of Klonz lub for the pump. Never run it dry!
I have the SMC kit. It works perfect for me. But if I was going to get one now i think i would try the AlkyControl.com kit because you dont need to worry about the pump dieing on you and it is also progressive.
