Thanks for the suggestions. I was looking around online and came across a regulator for a really good price and speaking with a few welding places around here they told me that with what i'm using it for that would work well because the co2 tank would last me longer regulated. It was $40 but hopefully it'll be worth it. Even if I don't save any money with it the thing looks pretty cool so I could possibly use it on a home brewing set up if I ever go that route.
