whether using a separate 12v system or using the flight battery I was wondering what 5 volt regulator you guys recommend for powering the camera and Tx as far as quality of build and noise suppression/cleanliness.

I was looking at a lawmate Tx that had a built in 5v power supply for the cam such but this seems to be a $50 price raise for what seems to be <$20 worth of tech. Not that cost is what Im worried about, I just want to do things right the first time. Ive seen different voltage regulators on the sponsoring sites but reviews are either hard to fine or nonexistent.

thanks
