Looking for a good on board charger curious to know what you guys use out there and what good thing and bad things you have to say about different ones from experience.

I have a DualPro 3-bank model that is 10 years old, has run 24/7 since I brought the boat home(other than when I'm fishing), and has never skipped a beat.  It's the only brand I'd even consider......

Dual Pro:  I bought a rebuilt one directly from Dual Pro last year at a considerable savings over retail.  It is one of the best things I have ever done to make fishing more enjoyable.  

My rig came with a Dual Pro.  After 5 years of hard use one bank quit working.  I checked around for another and couldn't believe the price.

I finally called Dual Pro and asked if they could repair mine.  I was told no but they would give me a $100 trade in.  So I have a second dual pro.  I am quite happy with that company.

I ordered a three bank Dual Pro charger with my boat 10 years ago and it still works good. Never had a problem with it.............Al

I did the same thing and when I sent the old one in, they fixed it and sent it back to me.  I called and the guy on the phone said, oh well, can you use another?  I laughed and said yes, thank you!  So now I have a dual pro in the boat and a second one in my boat storage unit, tending a few extra batteries.  

I would like a 3 bank but if you use the boat with any regularity, the starting battery stays charged.  I use a trickle charger on rare occasion in the winter.  I wouldn't even consider owning a boat without an onboard charger.

I did the same as Olebiker.  Bought a re-built one from DualPro.  Love it!

Stay away from the BPS units.  According to the reviews on the BPS web site, their units crap out after about a year or so.
