for those running 2 batteries

i know most of you say to use an isolator and then there are a few who just use a switch. from what i have read so far is that the switch is the cheaper way to go but the isolator is easier and better.

i am planning on getting 2 optima yellow tops to run my system. i have a pair of B530's and the 4 speakers and 1 sub in my boat. i also the boss 5 light bar, but never use it. using my phoenix gold tantrum 500 amp and one of the stock clarion amps, i have 2 main questions.

2 questions... do you think the extra money for the isolator is worth it? also, how often do you charge your batteries? i should be ok with using the slow trickle charge during the week and then using the boat all weekend, shouldnt i?

also, any diagrams of the 2 battery setup would be great.
i already tried looking in past posts but couldnt really find the answers i was looking for. maybe i just didnt look hard enough.

thanks
