This one is a little over your budget, but it's a great knife.

Benchmade is probably better known for their folding knives. This one is a fixed blade, and about the lowest cost knife I've found made with D2 steel.
While the scales aren't textured, the shape is "ergonomic" in that it has provisions to prevent thumb and forefinger slipping in use. In my experience, these are the things that tend to slip off a knife while you're field dressing...
