Welcome to the Forum Bill,
There are literaly hundreds of differing types, sizes and levels of models available that we could do with a little more information.
Do you fancy a static model, period ship, modern working boat, war ship, sailing ship etc etc and do you want it radio controlled, steam powered, electric power or IC power. I think that covers most (deliberately left subs out). The more info you can give us the better the advise you will get coming back and believe me when I say you have picked the best place to be for good advise.
All the very best,
Barry
