I just got my first MoD, a Dieter CQD Mk.I and I have to agree with QS. The materials are on par with MT, but the design and attention to detail seems to be short of Microtech's. For instance, the button that acts as a secondary lock for the primary plunge lock wiggles around quite a bit. It may not affect its function, but something like that is inexcusable on a knife with a street price around $250. This is the third CQD I've seen, and they have all been like that. Also, as QS pointed out, the MTs action is quite a bit smoother. I have 2 LCCs, a SOCOM and a Kestrel, and all of them open and lock like $200 knives should.
Bottom line is, I don't think you can go wrong with an MoD, but if this is your first foray into higher-end production tacticals, I think MT is a better choice.
