Look at the Spyderco Gayle Bradley. It's at the higher end of your price range, but worth it in my opinion. If you like a simple, well-made knife like the Sebenza, the GB should be perfect. It's very well-made; one of the nicest in Spyderco's collection. And the steel holds an edge for much longer than most steels, while retaining the toughness of cheaper steels. In fact, it's tough enough that they were able to put a really thin hollow grind on it without worrying about damage, which lets it cut as well as a Delica 4 FFG.
The Kershaw Speedform 2 is also one of the best values out there in terms of steel. Not as heavy duty as the GB, but it should hold up to whatever you're doing.
Looking at the specs, the price seems fine because it does look worth it.
Gahh. It would be so great if the handle was just half an inch shorter.
(I know it's just 1/2 an inch but...)
