Dat, Like Elliot said do some research and make sure that you know exactly what you're going to be using the boat for in terms of location, purposes other than fishing, fish you'll target etc...
We have a poly boat, its a Triumph boat from the US and we really like it. I believe that poly boats are the smoothest riding and they by far require the least maintenance due to the strength of the hull. I won't type the website in because it will probably get blurred out but put Triumph boats into a search engine or you tube and you will see the videos that show how amazingly strong they are.
Good luck with your selection,
Cheers
Josh
