Jim - I'd spend somewhat less than the 3K and leave room for mics, tripods, dollies and lights. Also, I'd buy a
Sony HXR-30U for $1999 instead of the AG-AC90 because it comes with an external mic, shoots 1080/60p, and has an incredible balanced optical stabilization system, as seen here:

As for the
HMC-150 - it is at least two generations old, lacks 1080/60p, has no external microphone and has a slow bit rate (21 mbps). I would avoid it.
Hope this is helpful,
Bill
