I would stay away from single-stage blowers, especially in Connecticut.
If you never get more than a couple of inches at a time and it's not the wet, slushy stuff then I'd disagree. Reality is though if you get more than a couple of inches at a time, it can be the wet slushy stuff or you have to deal with a snowplow burying your drive or sidewalk, it's not going to do what you need. I have a single stage, had it for years and it was ok till last winter (that and a good snow shovel). We got dumped on several times and no way could a single stage do much more than look at it and laugh. I now have multiple 2 stage units (planning on selling some this fall), a 4 hp 20" with a 10" impeller handled 8-12" snowfalls without much effort as long as it wasn't the wet stuff. It moved the wet stuff as long as you kept it moving or the chute plugged immediately. The others handled wet slushy stuff pretty much the same, except the bigger the engine the more you could move before having to stop. 7 hp 14" impeller did ok with the wet stuff, handled snow up over the auger too, though I did have to back up once or twice to get it all. I have a 10 hp waiting in the wings to see what this year brings. If you get that kind of stuff, hold off for a 2 stage - it will do you much better in the long run.
