With no flipper, I'd have to agree, the Kershaw Blur is a great choice. And, if you're willing to spend a little more, you can get it with different steels. The basic ones (Since July, '07) have 13C26 Sandvik, but there's also the S30V version, & there's a SG2 version (Still plentiful, but discontinued after a limited run).
If you're willing to try a flipper, I'd say the Cyclone (& mini-Cyclone at 4 1/4" closed) are good choice, too. They have a thumb-stud & flipper. What's nice about them is that you can easily switch it from an A/O to a manual if you feel the need.
If you don't absolutely need an A/O, then I'd highly recommend either the Groove or RAM. Both are great flippers & have great ergos.
Good luck with you choice.
