I picked up a Mastech MS2108A as a cheapie option for now.
You can get them for under $50 shipped - check eBay and Amazon.
Until I can scrape up the skrillah to get a Fluke for several hundred $, the Mastech is "close enough" - who cares if it's off by 20%?

@ 750 RPM idle, low beams on + fog lights on + A/C fan on max = 12.6V. Nudge the idle up to 850 RPMs or higher, and it goes up to ~13.6V.

With same loads switched off, from low idle and up nets between 13.6~14.5V.

It sounds like you got a better unit than I did.
I've never seen mines go over 13.9VDC, and it's an FD unit rated to 150A... :P
