For everyone rocking pressurized CO2, where do you go for tank refills? For personal purposes, I'm mostly concerned with the Metro Detroit/Ann Arbor area, but since it appears there are a lot of Westsiders on this board you are welcome to reply as well (former Westsider here
I want to put in a plug for Spears Fire & Safety on Ann Arbor's west side. I got my tank from them originally and have taken it back for refills a couple of times and it took them all of 5-10 minutes and I was back on my way. I thought nothing of it until spending my lunch driving around Livonia (work) trying to get it taken care of around here; the best I could find was a place where I could drop off the tank and maybe (?!?) have it filled by Friday. So I guess if you're in A2, they are the place to go!
Hopefully this will garner some kind of response. If not, meh, I tried.
