Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

OK.  I've read many posts about Ariens being a good model to go with.  I now am not sure which model to choose.  I live in Baldwinsville, NY (Northwest of Syracuse) which averages about 120-140 inches of snow per season (lots of lake effect snow).   I have a 45  foot paved driveway which is about 2 to 2.5 cars wide.  I guess the best model for my money is probably the Ariens.  But I am trying to figure out if it is worth it to go with another $500 and get the pro ($1000 vs. $1500).  I know what the differences are (OHV engine versus L-Head... the differential turning, etc).  I'll throw this in to.  I have a very bad back (L5-S1 disc degeneration) so I can't shovel anymore.  I need to get a snowblower that I can use without hurting myself and which my wife can use if I am in bad shape.  Any and all help is appreciated.  Thanks in advance.
