The Magnatek is more expensive than the Inteli-Power. It doesn't have anything like the Charge Wizard that will give a visual indication of what it's doing. I think that being able to see what's going on is the big plus here. Roger Hightower, N7KT WBCCI 4165, VAC, TCT 1975 31' Sovereign, '02 F-250 PSD Mesa, AZ mailto:n7kt@att.net
