I love my Pontoon! I believe that this is one of those case that you get what you pay for. So depending on how many days a year you will be using it should help point you into the direction of what boat. I have a Buck's Bag (http://www.bucksbags.com/cm_cat.asp?id=4
) Bronco Pontoon Boat. This boat has no problem going down a river, it is rated for class 4 rapids I think, not that I would ever try it. plenty of room for gear if you want to camp along the river and very sturdy. This boat can hold a lot and fishes great. I have a small trolling motor for lakes and it does sit high in the water and in the wind can be a bit unruly. The motor is a little awkward at times but serves a purpose. I also use flippers to help in those tight spots. It is great fun.
