question about co2 Regulators

[Naptown]

Hey guys, it's been a long time since I have been active here. Some health issues have kept me from brewing. Anyway, I have race weekend and my birthday coming up this weekend, so I have a need!

I want to treat myself to buying a keg for my birthday. I have some of my old kegging equipment and want to take an empty corny to a local brewery (I've done this in the past). I used to have a keggerator, but have since sold it. I do have the cornies, a picnic tap, lines, and a full paintball co2 container. I'm only missing the regulator. I want to purchase the least expensive (and maybe smallest) regulator to hang out on the patio with me.

I only know of the c02 regulators that have the 2 large dials. I would like to find something small and portable to regulate the gas from the paintball tank just for patio-type parties.

For example, would any of the junk from Harbor Freight work? Not sure this would work with co2 or not: http://www.harborfreight.com/125-psi-air-flow-regulator-with-gauge-68219.html

Please suggest a simple regulator for me to purchase before the weekend!

not sure if that HF part would work, I would think it would be difficult to get the right pressure since the range is so large on the gauge. You'd also need to get some sort of adapter for the threads, I think.
You probably want something like this: http://www.amazon.com/gp/product/B00WM44HRE/?tag=skimlinks_replacement-20
