I have to agree with the others. First you'll have to decide what you are going to do with the boat, race or play. What do you prefer? Electrics are a good way to start as that is the way that I began and learned a lot about how to set up a boat for performance, props, CG, etc. With nitro, a good starting spot is a 3.5 powered outboard tunnel hull boat. It is fast enough to be competitive for racing and to keep your interest plus aren't too difficult to set up for a beginner. Gas powered boats my seem to be a little pricy in the beginning, but you save money in the long run because of lower fuel costs, less support equipment and not prone to be temperamental during weather changes. Whatever you choose,the first thing is to have fun!
