I use the TOP (Tower of Power) from http://www.biglube.com/
It works great. Dick Dastardly is a Gentleman and very easy to work with. Seems the TOP and the one from Powder Inc. are the reigning champs around here. You will be happy with either. I can load 3 cylinder for my Remington in no time flat. Its very quick and easy. Just mount it on some form of hardwood board to give it a stable platform.
