I have a lot of ZTs, Spydies and a few BMs. It sounds like you are looking for a solid user. I have to say that the Hinderer XM-18 3.5 is just right. I would love to get my hands on an MP-1, but until then the XM-18 is probably my favorite. I love the ZT 0900 Les George, as well. I don't really EDC my customs, so hard to give ideas there. Oh, the Kizer Intrepid. I just pulled that out today and it is amazing. All these are in that same medium size range. That is my preference in general. For autos, some of my favorites are the ultratech, utx-85 and utx-70. I love every single protech I have. My two all time favorites are the Matt Diskin Revolution and the MD Wheel, but those are custom DA autos that cost a lot. I guess it boils down to how much knife you are willing to EDC.
For the lower price point, the Spydies are unbeatable (PM2, Manix, Native, Sage, etc etc)
For medium I would go Chris Reeve Umnumzaan or Hinderer XM-18.
For the 1k mark, hands down a Rockstead Shin if you plan to use it as an EDC. It is unbeatable.
For a usable auto, id go DA or side opening. If you like small, the MT mini socom elite DA auto is amazing.
Larger, tanto and good price - Protech TR4 or Kershaw Launch 6 or 7 can't remember.
Big, not too expensive - Brian Tighe Fighter auto (not the custom).
Beauty, Functionality and Amazingness at a high price - Diskin Rev or a MT Scarab or Hellhound
Anything by Reate, as well.
