Trolling and what options

I want to thank anyone with advice in advance, and please I know these questions have been asked alot but here goes another round. I have gotten back into boating after about 35 years, my uncle ran charters 30 +years for a few guys that are still out there, until he went on his own(slow retrieve charters). Back in the 80s it was about drift fishing and later trolling, but long lining it. There weren't the options of inline planers ,dipsy divers, big boards..etc. I want to get into trolling and putting some meat in the box...lol. one question I have is do you run shallow or deep behind dipsysor can I run the deep divers?? What's the better way to run deep bandits? Inline boards? I'm just getting back into things and hate to say I don't want to break the bank...but want to show the grandkids a good time.
