stand alone n2o enrichment AFPR?

I am putting together my own stand alone fuel system for my n2o setup and was looking for a good high pressure fuel pressure regualtor for a decent price. I saw one in Jeg's for like $220 are there any that work just the same for cheaper? I already have the pump and lines just need a 1gal. tank and the regualtor. I want to keep it with the higher fuel pressures b/c these NX nozzles work flawlessly as is and wouldn't want to make too many changes. The car is running very well as it sits on n2o. Later Clint
