Quality Fuel Pressure Regulators?

So Im finding so much mixed info online about these things I figured I would post here and see what you guys have to say. I recently aquired a Mazda B2200, long story, and its had a weber carb installed, all emissions equip removed, and an electic fuel pump installed so going back to stock is no longer really an option. The truck is in desparate need of a proper pressure regulator to replace the cheapo mr.gasket fuel fountain/firestarter thats on there now. I need to have 3.5 psi at the carb for optimal performance. Any recomendations on regulators/gauges? What have you had that worked or didnt?

Thanks.
