This might be old news but there is a 50% off discount from HDM 14 to HDM 15 until 11/30/2014. Just go to your account and select Upgrade from the side menu. Did anyone get an email about this? Maybe it just started but I don't really know? Haven't been following along much lately!
I just did the same. Hmm, no Recovery Media Builder yet! EDIT: There's an earlier post about the release and states that it's built in.
