I've done all 3 levels of carbine training at 88 Tactical (some twice just to stay fresh). They are day long courses up in Tekamah. Not a full gear, run and gun type course, more focus on weapon handling, malfunction drills, movement and cover/concealment drills and they bring in handgun transitions and room clearing in level III. $150 and 300 or so rounds are not to bad for some great training.
Have not done any, but they offer a full plate of handgun and carbine practical 1-2hr classes at the Omaha indoor center most evenings. Love to do the defensive handgun classes, but with the work schedule and 75 mile one way drive it is a challenge to schedule any of those weekday evening classes.
