Don't know if this post comes too late, but I have a Murry, I've had it for 3 years.  I love it, I use a snow blade on it in the winter and I really beat on it.  The blade is a third party (dont know which one), but the only thing that has gone wrong is the spring on the blade fell off when I slammed it into a pile of snow this year.  I later found it in the curb down the street (guess the city plow pushed it /w3tcompact/icons/smile.gif )  But the Murray products have proven to be flawless and rigorous.
