Inflatable boats?

In the last few years I've been getting out much more with my kids as they grow up and are able to do more with me outdoors. We visit the mountains often and stay with friends at their lake place. We all enjoy fishing and getting out. I've thought about buying a decent inflatable boat so we can get out on the water, lake and river. Do any of you water and cottage guys have some solid recommendations on what to look at?
