instrument voltage regulator

How much are the ones from RTE? I didn't see prices.

You have to add it to your cart to see prices. $50 plus tax & shipping for the one I looked at. Seems kind of scam-ish to me not posting prices, but I guess that is the new world.

I understand the attraction if you have a car you can just plug one into. But for a rally dash where you have to haywire it in anyway, seems like a lot of money to a cheapskate like me when there are cheaper options.
