I like benchmade knives a lot.

That said, if you've got time to look around, try to find someone who can do custom work, or a small-time knife builder. It's not in your price range, but I've got a knife for field dressing deer and a fillet knife as well from Eagle River Knife Company. The former was a b-day present from my parents and the latter was a groomsman present when my brother got married last May. I like having knives that aren't big-name manufacturers.
