I see that your location is Brooklyn, so unless you have a lot to do the 2 stage may not be worth it.
I live in Long Island so I have plenty of snow to get rid of. When I used a single stage for a 12"snowfall it almost wasn't worth using at all. 2 stage is a breeze and can easily handle up to 2 feet of snow.
That said, it cost 2-4x as much, is much heavier and is much bigger than a single stage.
