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

I am looking at purchasing my first snow blower.  My local shop carries Toro's and Ariens.  I live in northern NJ (morris county) and we had a lot of wet heavy/icy snow last year, so the wife has finally given in to the purchase. 

Our driveway is about 125' long and most of it is a about a single car lane, but it opens up to about 3 wide at the bottom.  Also my neighbor's drive way is adjacent to it and its about two cars lanes wide in front of their house and one car wide between the two houses.  So I'd have to throw the snow straight ahead when I am in the section between the two houses.

I'm currenty thinking of purchasing the Arien's 920013 (Compact 22).  Do you think a 6 HP engine will cut it, or should I be looking at a 7 HP?
