Unless you're really concerned about your user traffic hairpinning through the 
controller, I would personally avoid using local termination.  Controller 
termination has always worked out well for us, and seems to be much simpler 
from a configuration standpoint.

I don't remember all of the exact versions, but there were also a lot of crash 
happy ones for us in the 8.0 releases.  I'd personally say either the recent 
9.0 (MR3 or newer), or stick back to the 7.x releases, but avoid anything 
outside of those.

Long term, of course, I'd strongly recommend jumping off of Juniper, as 
they've pretty much given up on the wireless game.  We're in the early stages 
of switching to Aruba, and we're pretty happy so far.
