I have the Viair set up with twin 325cfm compressors and 2gal tank. I mounted it on the top of the wheel well. It is electric and draws some pretty good amps so you may want to make sure you have a good battery and alternator. I love it. the only thing I would do differently it to get the bigger compressors. Having said that I have never had a problem with what I got. As well living on a ranch it has proven to be invaluable.
The reviews section probably has reviews on OBAs.

After many thoughts I want to convert a ac compressor but currently with limited funds I was wondering if any body used scuba tanks to re air or as there on board air I have several and I think they hold 3k psi?

I'm going to say that a York setup is "best" if you can make it work.

I'm a little closer to having my On-Board-Air done. I've mounted the 1 gallon tank under the tub. I also fabricated a bracket to hold the pressure switch, T's, and fittings under the hood. To keep the under hood quick connect port clean, I used a fitting with a pressure gauge, this also allows me to know what the pressure is in the system. I also installed the ARB quick connect fitting on the rear of the Jeep behind the license plate. This should keep is a little cleaner, and not in a potential high damage area. Now to get the hoses from the compressor fabricated, and install the arming switch. The only bad decision I think I've made, is the arming of the system, will be by a switch that grounds the pressure switch circuit. If I'm not careful, I could leave the compressor on when the engine is off, running down the battery.

I think the two important properties to look for on a compressor are the flow rate and duty cycle. Viair makes some pretty good units with relatively easy install.

I did the Saden A/C compressor mod and love it. The only thing I changed in my set-up was where I mounted the air/oil filter. I had first put it in the engine bay and what was happening was the plastic bowl would crack from the heat. I moved it to inside the passenger compartment next to my tank and have not had an issue with it since. That's my 2 cents if you decide to go this route. Good luck!
