I know there have been tons of threads on this before. After putting my back out this past weekend shovelling, I can't put off the purchase of a snowblower any longer. What do I look for? What's a good deal? What don't I need? I'm not all that mechanically inclined. My driveway isn't huge - could basically fit three, maybe 4 cars in it if you really tried, so don't need anything massive.
