Well, might as well be the first- you have a wealth of options in that price range- all good knives, so here goes: Swamp Rat or Scrapyard if you want bullet-proof, Bark River has a huge selection and makes a great knife, Fehrman is a bit of a stretch $-wise, Rat Cutlery is definitely in the running. There are lots more than I can list. The ones I mentioned will get you started. I picked them because they all have good warranties and are all knives I have and like- it's going to depend mostly on your taste.
Just to make it harder, at your price point you can afford a custom from many of the knifemaker's that post on this forum. Have fun shopping!
