Depends on how you intend on using the boats. It you are going to put a small motor on it, the Momarsh boats I hear are the way to go. If you plan to do more paddling than motoring, the Carsten would be a better choice. I have a Hoefgen Duck Boat (similar to the carsten but much lighter) and I do love it. I wish I could put a motor on it to make it easier to go back upstream.
