Query: Best Charger Ever

I've done tons of research on what kind of charger to get for my marine batteries. I wanted to go cheap and bought the typical 60 dollar one at the local auto parts house. Once I did more research, I stumbled upon these Smart Chargers that help you maintain and Recondition abused batteries. I looked into it. I could not find one bad review on them. So I bought one at the local off road store. Charges my batteries like a champ. Had a friend who wanted to recondition his battery the old school way. We decided to test it with my new Ctek. Battery was low on fluid so we topped it off with water. Set charger to recondition mode. Charger did what it does. We have revived my friends battery. That was a selling point for me. Hope this helps in the decision making.
