I have several Bökers. As someone mentioned, the made in Germany ones suffer from the dollar-euro exchange ratio. Even so several of them are really quite good.
The Titan Defender was mentioned. I don't have it (yet) but I examined it already and indeed it's one of the best, most reliable liner locking knives I've ever encountered.
The compact Turbine 2 is a pretty good EDC as well. And check their folding hunter in ivory micarta.
The Taiwan-made Boker Plus ones tend to be relatively more affordable in the USA, and of these the CLB designs Trance, M-Type and Subcom are all interesting for their price. But the true gems of this series are in my opinion the two Exskelibur knives, licensed versions of a popular custom design, and they are very well made indeed for a good price.
