Spyderco Manix 2 S110V is a great suggestion, actually. The PM 2 is also well-loved around here. You'd be hard pressed to find better combos of ergos and performance.
You own a Blur so I assume you're pleased with the performance of aluminum handles and S30V steel. How about a Kershaw Camber? They just came out and are basically a flipper version of the Blur, just in a slightly smaller package.
The ZT 0566 is a great knife. I've owned a couple and they are quality knives. You can actually find them brand new for just a little over a 100 bucks, but if you scour the exchange you can find them for at or under a C note.
Kizer makes pretty good knives in your price range. You may want to give them a look, as well.
