Just thought I'd pass this along...found this place while searching. http://www.titanmotorsports.com/mrgashsefi.html
The website kinda sucks in that it seems like half the fittings aren't listed at all, or are listed without prices, BUT...they have the best prices I've seen on new, straight AN to NPT fittings. I got two -12 AN to 1/2" NPT fittings for $4.55 each. That's about half of what the same fitting would cost from Aeroquip.
