The York looks nice, but seems to be a good amount of work as well as a little pricey if you just need it for a set of horns. For the purpose of Air Pressure for Tires, etc, I could see it.
As bad as it sounds, lol, I like the idea of the Viair Ultra Light Duty, if you just need it for horns only. Once I get my 1-Ton on the road, I'll be looking into buying one.

I haven't checked into any reviews yet, but are there any negatives on it?
