Welcome Mollski,
as many people will say on here im sure. It depends what your after and how much you can afford to spend. Are you looking for a kit form, or to build from plans? have you got any previous RC/kit building experience. If we can get this info from you, then it can help us narrow down which models may be suitable for you. My first ever kit was the Robbe Paula III. Its a small harbour vessel, but with all of the additional working auxillary functions it can be made into a cracking little boat. this kit isnt too expensive, and can be a good starter (in my eyes) into RC boats. :)
