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

I just moved to Minnesota after being in the warm, no snow southwest USA.  I am new to the whole snow thing, so I have some basic questions about what I should get as far as a snow blower goes.  I see single stage and dual stage throwers, but can't seem to find out what the difference is??  Also, if all I am clearing is my driveway, which is 20' wide by 35' long, just what kind of horse power am I going to need?  I do know the difference in 2 cycle and 4 cycle engines, but that is about it.  I'm trying to get a head start on the whole snow thing and want to have a blower in my garage ready to go when the first snow hits.  Any advice is appreciated!!
