It's sort of the wrong time of year, but snowshoes can be had for a fraction of the cost if bought used. Like everything else, you pay for quality. If two sets of snowshoes look about the same and one is twice the cost, that probably means it's half the weight of the other.
The snowshoe matrix is weight verses floatation: How much less do you sink into the snow verses how much energy is spent lifting the snowshoe up for the next step. LOTS of snowshoes are far too heavy for the flotation they provide. Even more makes of snowshoe don't provide near enough flotation for anything but hard, dense spring snow. Try using them in fresh snow or in cold conditions and you'll only float a few inches above what a naked footprint provides.
The fad for a long time was to go with a smaller shoe on the theory that while you sink deeper, the lighter weight saves you energy with each step. I have NOT found this to be even remotely accurate. In my experience floatation trumps everything else.
Your local terrain and snow conditions will make a huge difference on which model will work best. In rolling hills with deep snow, nothing comes close to the traditional full size trail snowshoe. In steep country or in hard snow a smaller snowshoe with cleats works better.
Wood snowshoes are great, but they require a lot of maintenance or they will ruin quickly. It's not too bad when the snow is powdery, but once it crusts up you can wear the varnish off the bottoms in a few hours. Varnishing snowshoes isn't a huge job, but it's something you have to keep on top of. Synthetic snowshoes are basically maintenance free.
The two brands I've used extensively are Sherpa and Northern Lites. In my experience with both brands I prefer the larger sizes...larger than they recommend for my weight. I've found that while lager snowshoes are a little bit less maneuverable in firm snow or steep slopes, that's nothing compared to the effort of spending a day in deep powder and sinking in up to my knees with each step.
Lots of places rent snowshoes. It's not economical compared to owning a pair, but it's a good way to try out different sizes and designs.
