In my opinion there are only two worth considering...
Toro and Troy-Bilt.
Growing up in Pennsylvania in the 1970s and 1980s we had 3 snow blowers... a Toro Snow Pup that you could not, under any circumstances, kill. It was loud, it was smoky, it occasionally broke the fuel line, but it lasted for decades. Dad bought it in 1968 or 1967 and we didn't get rid of it until about 1980, and the second owner was still using it in the mid-1990s. The only problem with it was that it was small.
Replaced it with a Sears Craftsman that had a greater capacity. It was an absolute SOB to start. As often as not I would pull the spark plug and heat it with a blow torch to get it running.
The third was a Murray. No clue what possessed my Dad to get that one. It was absolute trash.
However, the basis for my recommendation comes primarily from friends and acquaintances who have had a variety of Toros and Troy-Bilts. Virtually all have been pretty much bullet proof, durable, and reliable.
Fortunately I live in an area of the country that doesn't get much in the way of snow, and only gets BIG storms every 5 or 6 years or so. So I just have a shovel. :)
