Best for quality and durability is the Tanaka motors,match it with a Nils auger and you have a sweet ice eating light weight reliable machine... but they are not USA made although will last you a lifetime, and a 7 year warrenty...Mine costs me about $4 a year to run on gas/oil, spare blades are expensive up front but they are able to be resharpened and last 3-5 years before needing sharpened, maybe more depending on amout of use....2 heads will last you a lifetime also so only a 1 time investment on heads and reshapening runs $20 plus shipping costs to MN, the guy who resharpens them will return them better than new...
