It's hard to give you suggestions of gear when your budget isn't known. Also how much space you have when you travel.....ie....are you using an SUV or a car or something. I would recommend powered because it's easier set up and breakdown. If you plan on doing large events then the old fashioned speaker and amp set up would work better because you can add subs to what ever speakers you decide to go with. I started with R@dio Shack 12" speakers (4 total) and one amp to get me started. I put many miles on those things. So start with what your bugdet is and decide if you will be expanding and then do your research on brands you may prefer.
