Many of the Becker knives are under $75, like the BK16.
The Queen Light Hunters are under $75 and you get D2 steel and beautiful bone handles.
Nothing wrong with the Buck 119 either. :thumbup:
If you'd like to save even more money, KaBar has a line of imported hunting knives with stacked leather handles and stainless blades. I'm impressed by the build quality of these. The Bowie is $45 and the Working Hunter is $32. They have several other models too.
For whittling you might be best served by a smaller fixed blade knife. Instead of the Buck 119 look at the Pathfinder and Woodsman. Check out "bird and trout" sized knives or "Little Finn" style hunters.
Scandinavian brands offer many choices in your price range too that would make excellent whittlers, in fact some brands have knives specifically designed for that purpose. Mora, Ahti, Marttiini, Järvenpää. Lapin, and others.
So many choices. Good luck narrowing it down.
