I run in a 4mm drop NB Minimus Trail (wide width, of course!). Zero cushioning, but I like it that way as I'd be running totally barefoot if I could get my skin to cooperate. Transition from a custom orthotic fitted high stability, high drop NB shoe took me months and I wasn't a high mileage runner to begin with...

My husband recently switched from a 12mm drop shoe (a Nike style, not sure which) to the 4mm drop NB Minimus Road version. The Road has more cushioning in the forefoot than the trail does and it suits him well. He wasn't putting in a lot of miles before, so his transition has been easier than it might have been for a serious runner, but he's loving the new shoes. He comments almost every run how he enjoys being able to feel the road and precisely how his foot is positioned, so that he can immediately correct it. This is after we took a Chi Running clinic (which is what prompted his shoe shopping in the first place), so he was already working on improving his form before making the switch.

The NB Minimus Road is on sale at most stores right now for $60 ish because they are replacing it with a new design in the spring. So if you don't mind not being able to keep the same shoe going forward, it might be a nice, inexpensive, low-drop shoe to try.
