Training I took while I was living in Kzoo:
MDFI- 6 courses
Sentinel Concepts - 3 courses
Will Petty- VCQB and AVCQB (via MDFI)
Larry Vickers SPR course
Larry Vickers 1911 course
Since moving to AZ:
Gunsite - Pistol 250 and .223 courses
Scott Jedlinski Modern Samurai RDS course
Two Sentinel Concepts pistol courses
I can't really say I got anything more out of the 5-day pistol courses from Gunsite and 5-day carbine course than I would get out of a 2 day MDFI or Sentinel Concept classes. While MI may not have the shear volume of training opportunities that we have here, it's really Quality over Quantity. I am a big Gunsite fan, but their teaching is a bit rigid and they don't really update their methods like Trek and Yeti do.
You won't go wrong with either Sentinel or MDFI. Trek really has you check your ego before you step on the range. Probably the best training I've been in for a mixture of men/women and beginner/more advanced. Hell, that's my wife on their website holding the FDE Glock 19 on the "Ego Free Training for Everyday Life" part. She really liked MDFI as well and took 3 classes with me. Couple of Yeti's as well.
