I guess the question you can answer for all of us is what it is that you want to buy? Can you describe it better than 'jet boat'? That may give us a hint as to what we can suggest.

As for me, I am pretty much an RC Flyer and have not done boats. I've also done cars, by the way.

Tower Hobbies is one good place for a lot of the RC hobby products. Did you look there? In addition to a great selection of all sorts of products, you will probably get a pretty good price from them too.
