John,
I purchased one just over a year ago and love it for stillwater fishing. I mainly use it on o'neill forebay and san luis reservoir for striper fishing. For me, it has a number of advantages over a float tube or pontoon, but the biggest one is that I can stand up and cast / fish from it. I absolutely hate casting shooting heads and heavy sinking lines from a float tube, so this was my main motivation in purchasing it. I have not used it on moving water yet, but to me it is more of a stillwater craft, similar to a pram. I haven't used it with a motor yet, but I think it would do great with a small trolling motor or 2 hp. If you want to give it a try, we may be able to meet up some time. I am actually moving in about a year and have been debating whether I want to sell it or move it with me even though I will be purchasing a "real" boat after the move. PM me with any questions.
