It's hard to beat the plastic handled Moras for value per dollar. They will take quite a bit of abuse and keep going. Note however that they are cutting tools not prybars. I have noticed that the carbon steel blades are vulnerable to corrosion where the blade meets the plastic, creating a potential weak point over time; not a negative, just something to be managed.

I like the Opinels for their aesthetic quality and the edge they will take. Great for whittling. However, they don't strike me as terribly robust from an abuse point of view. Worst, the wood swells if it gets wet and you can't get the blade out without pliers. Not a good choice IMO.

Don't forget about the Old Hickory knives made by Ontario. Not tacticool, but very much the type of blade that won the West (as the phrase goes). Very inexpensive, with 1095 carbon steel that takes a wicked edge. I think they make a dandy bush knife, though you have to make your own sheath. Some blades are thicker than others.
