RE: Which boat?
All of these boats are VERY different from each other. If you want realibility, then don't go nitro unless you really know how to tune one good. I have the Profisherman and I like it alot. It handles great and has different handling characteristics than any of my other boats. I have upgraded the motor and prop and it runs about 6mph faster than it did stock. I hear good things about the Traxxas Blast, but really don't care for how it looks myself. The Reef Racer is a small pool toy. Are you looking for something to upgrade to go faster one day or are you just wanting to play with it like it is? The Blast is easy to upgrade and so is the Profisherman. The Blast is a inboard, the Profisherman is an Outboard. Like I said they are very different from each other. Its really up to you and what you are looking for. Both the Profisherman and Blast are very realible boats.
