We have two pair of the original Sherpas here; they're excellent snowshoes. (My wife dislikes the bindings, but I like them for their simplicity and reliability.) The original manufacturer went the way of all flesh years ago. Successive owners of the name ran it into the ground and are now out of business. (I never cared for their designs. YMMV.)
A Canadian firm, IRL Supplies, "gets it" and sells an explicitly Sherpa-like
Arctic Trekker , as well as Sherpa repairs and parts.
I also have a pair of MSR Denali Ascents. They're the bee's knees on steep terrain, especially when it's icy. I love the bindings -- easily manipulated with gloves or even mittens at subzero temps. But I strongly dislike the noise they make with their (admittedly tough) plastic decks. If you get MSR snowshoes, be sure to get the flotation tails simultaneously, unless you're relatively light. And be sure you get the tails that are compatible with your particular model of MSR 'shoe. I would never buy any in the MSR plastic line as my 'shoe of choice for hare and rabbit hunting -- they're way too noisy. And their metal-framed Lightning line has some durability issues.
We also have a pair of Tubbs aluminum-framed 'shoes here which my wife likes a lot. Personally I find the current Tubbs and Atlas bindings to be fussy. I'm also a strong adherent of strong and simple when it comes to bindings that I need to work
always way, way back in the backcountry when it's way, way cold. Not a fan of fussy for that reason.
If I were buying 'shoes for sneaking around after hares and rabbits and mebbe deer, I'd actually buy a pair of ash-framed, rawhide-laced (okay, maybe neoprene-laced) traditional snowshoes. I had two pair as a kid and wish I had them now. They're quieter than everything else and adequate for everything but mountaineering. I would stay away from the true bearpaw style at one extreme and the true Alaskan style at the other. Most everything else in between would work well as an all-around 'shoe.
