I have a 2 stage Ariens that is an awesome machine. My driveway is also 80+ feet, uphill, with curves to boot. The thrower works great and from what I have heard about the personal plows, you might want to stick with the thrower. It gets tough if the driveway is not flat, and if there are curves.

I have this one and I know that Ariens makes top notch products.
