after a couple weeks of looking at the available gauges, I finally decided on getting the 52mm Blitz BL (Black Light) series. BUT i just found out that they don't make them anymore in the 52mm size. So now I am back to being clueless . I'm liking what I have read about the defi gauges and I am leaning towards them at the moment. What others should I consider?

How about HKS, Greddy or Apexi?

I run Defi and like the setup. I will keep the Defi setup and get more. I only have boost gauge hook up for now.
