I owned a G3 for several years and it was a well built but very heavy boat for it's size. Just depends on what you want to use your boat for. If I had the time and strength right now I'd build a boat. Many of the guys on this site have built some real beauties and I would seek their advice on what size and type to build. Pride of ownership has to be something special when someone asks you where did you find that boat ? Then you answer, "I built her".
Good luck and remember, "There is no such thing as a perfect boat".
