I'll play some TvP Mech games over the next week and post some replays for you. There is a very delicate transition requirement and the general approach is, "I've already invested all of this money into X Infantry Upgrades and X Barracks, so why would I transition into Mech when I can just supplement with Ghosts and Medivacs?"

I generally stop making Barracks once my third goes up and begin the transition. On a map like XNC or Tal'Darim, it makes dividing the map so much easier, and allows you to take additional bases unchallenged. I would never, ever recommend it on a map like Terminus or Crevasse though. It all comes down to play style too. Some people are suited to using drops and infantry mobility to end the game on 2 or 3 bases, others are comfortable with playing a more passive style and taking half a dozen bases.
