onboard battery charger ?

[line dancin fishing team]

I had a promariner 20 2 bank on my boat. It was one just over two years and quit working. I called promariner and was basically told tough luck buy another. well i started doing research adn found tons of complaint for the same problem work for a year or two and dies. So i am not going to buy another promariner. I have read a few good reviews on other companies out there and am tring to decide on a new system. What do some of you guys have for an onboard and how long have you had it. Also like and dislikes. I am thinking of another 20 amp size charger.
