fuel pressure regulator source

Where are people buying reliable fuel pressure regulators?  I got a taiwanese 
one from Vicky B which worked once then not the next time I started the car 
(no gas would go through it) then a chinese one (Mr. Gasket Brand) from my 
friendly local speed shop which did the EXACT same thing.  (turn on fuel pump 
no 
gas.  Take off regulator and check gas before it, plenty)

Has anyone found ones that work?  This regulator issue is NOT helping me 
diagnose my tuning problems.

Thanks,
