For built in chargers I've had a real bad expierience with 2 brand new xantrex chargers. I changed to the ProNautiP and haven't had ANY problems. The one I bought was a 60amp and could charge 3 different batteries at the same time. Set it up for AGM, Gel, Flooded... $600. It doesn't look like it is available any more but the 50 and 30 amp are. 30amp= ProNautic1230P = $500.
I also had a real good expierience with a 40amp Stanley portable I got from Lowes. $100. When the second xantrex died the Stanley got me through the delivery and I still use it for all types of 12V battery projects. It also has an engine start mode, battery recondition, and alternator test modes. Maximize your charging current but don't exceed the rate for the capacity of your batteries. If you pull in late for a night at a marina you want to ensure that the batteries are full charged for an early departure. I have even pulled in for dinner and then anchored out. If I recall, flooded wet cells are limited to 25% of their rated capacity, gel = 30%, AGM = 40%. So from the sounds of it you probably have about 200A/hr total capacity so you could go as large as a 50 amp charger. This would ensure you could recharge in about 4 hours. Also bear in mind that in order to prolong the life of you batteries you should avoid discharging more than 50% or below about 11.7v no load voltage. With only two batteries, it would be smart to keep them separated into a starting and house battery. This ensures that your house loads don't jeopardize your ability to start the engine. All of this being said I've actually found that my time motoring to the slip and anchorage were often sufficient to keep me topped off. Your stock alternator is probably 30-50amps. You might just keep your costs down and use a portable till you start cruising full time. Good luck.
