CO2 In Milwaukee
 

Tanks:
Frugal Home Brewer (the have shops all over the greater MKE area)
5lb ~$40
eBay

Refills:
Otto's (liquor store), can fill upto 10lb tanks
~ $1/lb
I know for sure the one on Browndeer Rd, and Cedarburg, does refills.


If anyone has any other CO2 resources for MKE area fill us in.

I am just starting the planning stage of a high tech setup, reason I am mentioning this is cause I am a bit southwest of Milwaukee, and the ones you listed seem to lead more to the Northside of town. So while I plan, Ill do some pricing and edit in some south/ SW side sources as I find em.

Valley National Gas on the far south side (13th and College area) will fill beverage sized tanks. Ask for Mark at the counter and tell him Carl sent you.

Garys Beer and Liquor on Howell and Ryan is nice to work with. A 5lb tank runs $60, and refills are $6.50.

I just bought a 5lb-er from them today.

Recently got a DIY Paintball CO2 kit from SnS through JaggedFury. I'm going to go ahead and recommend Paintball Dave's in the Third Ward. They were out of 20 oz tanks so the guy gave me a 24 oz for the same price of $24 filled. Refills are $2.

I have my tanks refilled at discount liquor on Oklahoma (1.25/lb). When it comes time for hydrostatic testing I swap out tanks at valley national gas (between collage and Rawson in an industrial area off 13th street).
