I have a Karcher K series that was pretty cheap from Walmart. I know the life expectancy of the cheaper electrics isn't too long. However, I only use it to wash cars, so it's more than enough. I figure I don't need super pressure to wash cars. All Karchers consumer models come with a 1 year exchange warranty ( you cut of the tag and cord and they mail you a new one). So far, so good. For my use, its real hard to me to justify spending more than the $129 Walmart charged me for it. As, it works great. I also bought and extension pressure hose, so now the machine can sit in the garage and I can do a whole big truck without having to move the machine around. I won highly reccomend this for anyone interested in one of these lower cost machines, as 25 ft of pressure hose means you will likely have to move theachine around to get around to different sides of the car. I also just ordered a MTM Hydro Foam Lance, and I'm hoping this machine has enough power to make at least decent foam.
