Anybody know much about them? I recently moved into a new house, and have noticed that the dishwasher is pretty much worthless. Dishes come out with food on them unless they go in completely clean. At this point, I'm just doing the dishes manually. I was thinking about buying a new one, but I really have no idea where to start. How difficult is it to install? I could probably get one of my uncles to do it, but I like doing as much myself as possible. Any thoughts? TIA!
