I purchased a 15' raft from Fishcraft down in Sisters, OR about 6-7 years ago. It has served me well. I believe the company is called Riverman now but not sure.
Basically it's a Star raft with an NRS frame. If I knew then what I know now I would have purchased them separately and constructed it myself. What I like about the raft is, it has a tunnel hull so the center of the boat rides high up out of the water reducing drag and gives you more of a feel of a cataraft.
I guess the big thing you need to think about is how you intend to use it mostly. This boat is wonderful for loading up with 2-3 guys and all the crap you need for a week on the river.
I originally purchased it for the family trips and extended fishing trips with friends. When I take the family out were talking 2 adults, 2 teenagers and a large lab and it's perfect for that when floating the Deschutes / Rogue / Salmon.
However it can be a bit big for the Yakima which is where I spend most of my water time and because it's a raft it has a fair amount of drag making if difficult if not impossible to anchor mid river in those big summer flows. I really need two boats.... Got to talk to the wife about that.
Check out the photos for an idea of the configuration.
