Steven is great there, but you may want the greater selection a knife store or site offers. That said, the minigrip is a great starter knife. If you search CPF for knife suggestion threads, you will see the Griptilian line mentioned again and again. Very comfortable, the great Axis lock, sheeple friendly colors, two blade styles, two sizes, even a fixed blade! My wife edcs a minigrip.
You are luckily not starting in the dregs, but jumping into a nice solid high quality knife, so it will only get better. This price range allows you many possibilities, and you won't go horribly wrong with choices from Spyderco, Benchmade, Kershaw, even some of the nicer Columbia knives you can get from Steven! And you've received some very good suggestions already.
