Great beginner's kayak.
My wife and I bought Quest 10s a few months ago. It is my first kayak and I am very happy with it. It's very light, and I have no problem lifting onto the roof-racks on my own, although my slightly smaller wife (I'm 6', she's 5'6") struggles a bit. I am a fly-fisher, and it is stable enough to cast/false cast without problem. It is easy to paddle, and great fun. I have only paddled on the lovely Lake Burley Griffin, and other lakes, so can't talk about white-water, but if you just want to mess about in boats, then this is a really good choice.
