I wanted to share my experience with these. I have owned a pair of 30" Northern Lites Backcountry Elites for six years now. They have treated me extremely well. The bindings work fine. A few of the plastic clips that hold the decking to the frame have worn down and broken off, but this hasn't affected the performance of the shoe at all. The cleats are aluminum, but they have not worn down nearly as much as you might expect. One thing I specifically like better about these than mountaineering-style snowshoes is that the tails don't grip too much, which allows me to descend smoother and faster. With MSRs or Tubbs Flex, I would have to stick every step rather than glide down the trails. Finally, the bindings don't have the clevis pin that the other models use, and I feel good knowing that there is nothing that might break and leave me stranded out in the woods. I spend a lot of time off trail, and the 30" size has always provided enough flotation. As was mentioned earlier, they are not good on icy or rocky terrain, but that usually means crampon or Microspike territory.
PS, you can buy them on Walmart.com now
