I've got a pair of Northern Lites and I love them, too. I must say, however, their warranty and customer service are awful. When part of my cleat sheared off in crusty snow early last winter, I called about the warranty and the owner of the company told me he would be too busy to fix them until spring...
I sent them in at the end of the winter and he told me they were too worn out to fix, and that it would cost $100 plus $15 shipping to refurbish them after one winter's use - which I refused to pay. So much for a warranty. It was quite a hassle just to get him to fix the original problem and not charge me additional shipping fees for a manufacturing flaw in one particular batch of their aluminum cleats. This is too bad, since they are otherwise the best pair of snowshoes I've ever owned.
