Man, thats a pretty wide range of knives. I am not attached to the hip with any particular hunting knife, but Don Llewellyns (Valkman here on THR) little skinner is a pretty good deal. It may seem wierd, but a small blade like that, coupled with a larger handle, actually makes skinning substantially easier.
For production knives, gazillions of people have bought Buck knives and used them with complete satisfaction. No reason you can't too, and they have a pretty wide selection of fixed blade hunting knives, all of which fall into your price range.
For a pocket knife.... Cripes, I can't even begin to list how many "good, durable" choices there are out there. A lot of it depends on what you want to use it for and personal taste. Personally, I am a fan of Spyderco. I will buy knives from other companies and everything, but with everything else being equal, I will buy from them before anyone else. If your taste runs to slipjoints, which can be handy as all get out for small skinning chores, I personally like Case and Boker. I am not a huge slipjoint guy, and so my taste reflects simply the most popular choices there are in that arena. I also am a very big fan of the Benchmade Griptilian knives. The axis lock they use is a delight. The Kershaw Leek, as mentioned by several, is a fabulous little knife, as are a few other of Kershaws offerings. You know, you can't hardly go wrong with a good ol' Swiss Army Knife, either. I happen to prefer the Super Tinker, but there are a bunch of choices out there. You will find that there are a ton of guys here that make a SAK a part of their daily dress. I personally carry either a Spyderco Endura or a Benchmade Griptilian on me every single day, but I also keep a SAK in my work bag. The knife part is handy (and those blades take a heck of an edge), but I actually do use the tools (specifically the scissors) regularly. Along those lines, you may actually find more usefulness in a multitool, though since you specify pocket-knife, I will assume you mean just that.
My best advice is to take a gander at some of the big online knife stores and shop around. I like looking at A. G. Russell and New Graham. Between those two, you should be able to see a representative example of just about anything you would want to look at.
Don't be put off by the cheap prices on the Moras and Opinels. They are good, proven, practical knives. You may not care for the aesthetic or something and that's fine, but don't discount them just because they are cheap.
