I'd agree that the Delica is really nice in that price range. Any Spyderco in VG-10 is recommended, as well as any Kershaw in 14C28N, like the OD-1 or the Skyline.
The Leek is nice, and I love mine, but the tip is really delicate. This can be a plus or a minus depending on how you intend to use it.
The steel isn't as good as the above, but the Cold Steel AK-47 knives are quite good if you need a really tough knife that isn't very heavy.
If you need a sharp edge that will stay sharp for a long time and handle fairly rough work for a knife (still knife-type work though, no prying or whatnot, of course) the Kershaw Needs Work is great.
It's a bit cheaper than your price range, but the Svord Peasant is a great knife for EDC tasks, and is very sheeple-friendly if that matters to you. Also it is a cool knife to have, and is just fun to use. It has a carbon steel blade, so some Fluid Film or Sheath might be in order to protect it from rust. The carbon steel blade makes it an excellent general utility knife too, of course.
The Victorinox Farmer in Alox is a very nice piece in the $32 range or so.
The Ontario Rat-1 is a modern classic.
The Buck Vantage Avid series is a great blend of value and cutting ability.
I love my SOG Flash II for EDC. The lockup is a tad loose, but it is an excellent knife otherwise.
