Personally, I think you have a good situation for a good electric single stage. I like my Toro 1800 Power Curve. [#38025]
You'll be storing it in your basement, in effect, and this eliminates the worries of gas cans and gas tanks in your house. Make sure you have a GFCI outlet handy- buy a decent cord, a spare auger, blade and skids, and you're good to go for a few years. when you're done using it- dry it off- give it a shot of WD40 and hang it up on a hook in the garage. a year later- just take it down and go. [the spare auger, blades and skids are because the auger & blade are plastic-- I've managed to break each by being stupid. Dealers don't stock parts for these things, so I order from Jack's online, keep a kit ready, - and get back in business in 20 minutes.]
If you insist on gas, a single stage would still be your best bet. They clean closer to the pavement, and for up to 5-6inches snow they can be faster than a 2 stage. Also for wet snow, in my experience a single stage tosses it further than a 2 stage.
I did my 2 car wide, 6 car long, steep driveway with 2 large turn-arounds for 3 years with my 1800. Near Albany, NY- about 100 inches of snow a year. Last winter was worse than most & we had three 20+ inch snowfalls so I bought an old 2 stage Bolens to play with this year. Still- 1" is shovel work- 2-4 is toro electric- and over 4 I get the bolens out. [ we have mostly drier snow than you'd get]
