I currently have three McMillans, including an Edge, but I actually like Sako's "$20 plastic stock". Though they like to call it a two step injection molded soft touch stock with grip panels. You can buy one through Brownells, but even at dealer cost, they are fairly expensive and are by no means cheap.
For me, the shape and ergonomics of the Sako stock fits me like a glove. Cannot speak on its fit for another, but for me, I cannot stress enough how well the Sako stock fits me. The Sako stock is surprisingly light, much lighter than I had expected, so I'd reduce little to no weight with an Edge. The Sako soft touch surface and grip panels work extremely well. In cold wet hands, the soft touch is actually better functioning in the field than the surface finish on my McMillans. The Sako stock is surprisingly stiff and appears very durable. The action screws hold torque and the barreled action doesn't walk around, resulting in excellent repeatable accuracy. So, switching to an Edge at this point has little value being I'd lose little to no weight, it would give me no greater durability, it would give me no greater accuracy, it would give me no better ergonomic fit, and it would actually reduce performance in wet and cold conditions.
Of course to satisfy the snob factor, it would be nice to have a custom layed up stock, and I probably would get an Edge if the factory stock ever breaks. But, for pure fit and performance, I see absolutely nothing wrong with the "$20 plastic stock" on my Black Bear. It rocks
