Craftsman review: snowblower life expectancy

We bought a Sears Craftsman Dual Stage Snowblower from sears in Nov. 29/03 we paid 1799.99 + tax totalling 2069.99 (400.00 per year). We've been trying to get a part for it since Nov 2009 ...backordered... today we received a call (Jan 25, 2010) that the part is no longer manufactured by the company and the life expectancy of a snowblower is 5 years and therefore the snowblower is rendered useless . So by my calculations...snowblower..400 per yr + gas + oil + extra parts + time...it would have been way cheaper to have my driveway plowed by someone trying to make a living at it @ 20.00 per storm. Sears will never sell me another item...
