Welcome to the madhouse....
You don't say wether your interested in building a static or working model, and an idea of your skill level would help users to give you some ideas as well... Have you done any modelling before? Even if it wasn't model boats?
There's no point taking on something which is beyond your abilities, but having said that, it never ceases to amaze me how some people who have never modelled before can turn out absolute masterpieces.... So don't let your skill level put you off - If your really determined anything is possible!
Hopefully some of our American users can help with suggestions for a suitable subject to model?
