I borrowed a friends 2 person pontoon for a float and was glad that I did...so I wouldn't buy one! I found it very difficult to enter and exit the center seat from where I was rowing and nearly impossible to fish two guys from the boat. Just for getting from hole to hole it worked ok with the exception of entry and exit from the boat. The addition of a floor vs. foot strap for the rower may have made these problems non existant but the way the boat came set up from the factory it left a lot to be desired.
I totally agree that you get what you pay for in this market and going cheep is not the way to go. I recommend you take a look at some of the whitewater companies offereings (NRS, Maravia, Aire, etc.) and see what they have in catarafts that may interest you as well.
