It is made in South Carolina, the US is their largest market, they OEM many models for Sears, and it is used as commercial lawn maintenance gear. It may be weaker in some regions. As you set, it can be regional. In the US Sears lists the low end Husqvarna's as Husqvarna. In Canada they OEM a custom configuration as a Sears:

In NJ the Husqvarna seems fine from an availablity and service perspective. Establishing whether it is a superior machine or not is a bit harder. Note: I don't find the base model compelling although at its near MTD price point it may be worth considering. The 30" base model has left right steering and comes with a 414cc LCT to compete against a similarly featured MTD about about $100 less expensive. For comparison, the less expensive Ariens Sno-Tek line seems less expensive, but well built. Like a 1996 Honda Civic or Toyota Corolla, back in the day when they were basic, solid, machines.
