Query: Multiple defective parts - avoid

My experience echos that of others here. I bought the first one in fall of 2006, used it once and had the drive train break in < 5 minutes. I exchanged it, figuring it was a fluke. Didn't use the new one at all until summer of 2007. Upon the first time using it, the string advance was obviously broken from within the first 5 minutes of use. It managed to auto-advance the entire spool of factory stock string in the time it took me to do half of my front yard. I was picking up chopped string bits all over the yard that where anywhere from an inch to 4 inches long. Sometimes, the string would be advanced so far that it would get caught and pop the spool cap right off. My neighbor enjoyed the amusement, though after the 5th or 6th "Good Grief!" range out from me while trying to use this thing. I had to borrow his to finish up my yard. This Grass Hog is going back for store credit. I wouldn't even take one for free it's so bad.
