Local dive shop closed, where do I get hpa now ?

Thanks a lot old corps, lol
that was a lot of reading, the gist I get from it all is that you may do better, but you ain't gonna get any cheaper than the Yong Feng.
i would probably go with the 110 model, for ease.

Thank you,
Mitch

Thank you Moe,
i have a 40 cu ft scuba tank. My need for speed and power is under control..... Sometimes.
Have thought of going with a 4500 tank but not just yet.
A full 3000 psi fill lasts me quite awhile. How long do you think it would take your pump to fill it ?

UPDATE

Bought a scba to scuba adapter from Northshore Compressor in Silver Bay, Minn. Nice quality unit. Gave it to a local fire dept. They loved it and are giving me all the hpa I need. I believe that I will also buy the scba to paintball adapter also. It looks like a 4500 psi tank is in my future. 

Thanks to you all for your advice and opinions. The Yong Feng compressor is not out of the question, but not just yet.

Good luck to all.

Mitch
