Being here in New England my whole life, I have used many snow blowers.
There are all kinds of factors to consider, and you may find that one man's meat is another man's poison...
I have a cheapo big box unit, 28 inch throw, 10 horse B&S motor. The unit is made by Husky I believe, but not labeled that way. It works well, and has for the last 10 years. I like a motor I know, like a Briggs or a Kohler, as I have good luck with theirs.
I clear the 87 year old's drive way across the way each storm, and a couple years ago he insisted I take his Honda. It is 28 inch, 8 horse. (Both are two stage)
I like mine better, in spite of the fact that it is older, and 1/2 the price of his. I have drift breakers on mine (Wing type blades that stick up from the mouth of the auger housing for breaking into drifts taller than the snowblower entrance) that his does not have, but other than that, both have about the same features...
His controls are a tiny bit better, and has one more remote handle for adjusting the top deflector. I will admit his engine is quieter, and his machine will throw the snow much farther than mine. On a normal day, mine will throw the snow 25 to 30 feet max, and his will throw the same snow 40 to 45 feet.
Some times that extra throw is very convenient, sometimes it is not.
All of the single stage throwers that I have seen use a rubber blade instead of a serrated metal one typical in a two stage unit. That will frequently sweep and clean a small snowfall much better than the two stage. So for light snow, a single stage is sometime superior, even though it does not throw snow as far.
Also, in case you are not sure of what everyone is speaking about with single stage or two stage, it has to do with how it collects snow, and how it throws it. On a single stage blower, it has one rotating set of blades, kind of like a large rotary mower, that is horizontal. That rotating set of blades scoops up the snow and forces it out a portal in the top of the housing. That portal has a short tube, with a deflector at the top, and you can rotate and adjust that portal to toss the snow any direction you choose.
A two stage has the same horizontal rotary blades (Usually metal) but feed the snow farther back into a chamber with a fast moving fan that feeds the snow up to the portal like before. The advantage is that it can move more snow, and because there are two stages, you can have the larger horizontal blades moving slower and bite into the snow better, and have the second fan stage mover very fast, with throws the snow with more force, and therefore farther.
A second factor with single stage vs two stage is that most single stage blowers that I have seen do not drive themselves. The blade does contact the ground which will have a tendency to drag itself forward, but the wheels do not drive. A two stage machine almost always has a transmission of sorts and a drive mechanism to move the wheels. This is very important if there is any incline that you must navigate. Any one with a self propelled lawn mower vs a simple push mower will know what I am talking about.
Good luck. Have fun. Consider buying a test machine of one sort, and use it a few times to figure out exactly what you like and do not like, then buy your perfect machine.
I have always had good luck and good finances to buy lawn tractors in October, because I can make a better deal, and snow blowers in April, for the very same reason.
