There's 2 different ones I can recommend to you. The Toro Model 2450 is a single stage type, cost here is $589, then add another $100 if you want electric start on it, though it's not really necessary. This thing will clear your driveway and be pretty much maintenace free besides the norm., but if the snow is heavy and wet there's no single stage that can handle that as well as a 2 stage. Plus with a single stage you have to mix the oil and gas together.
A lower priced 2 stage would be the Airens 5520E This is a 5.5 hp blower and cost $599 here, add $100 for electric start. This thing will move the snow for you, wet or dry. I have the 7hp model which I bought 5 years ago and couldn't be happier with it. Didn't want to have to be concerned with ever buying another blower, this thing will last a lifetime. You may even want to consider an 8 hp to get the job done quicker, especially if you get alot of the heavy wet stuff.
There are alot of brands to choose from, Airens is the cadillac, heavier gauge steel and top notch quality. Toro and Simplistic are also good brands. I'd stear clear of the MTD's and the Murrays if you want one that will last.
