5pm on a Friday evening, and I just picked up a medium sized oxygen and slightly smaller acetylene cylinder, and Juan was helpful and showed me a selection of sizes. I opted to buy the cylinders for roughly $170 instead of renting, and he gave me the first gas fill free. He also helpfully pointed out that I would need an adaptor to go from my small portable welding rig onto the full-size type acetylene valve on the cylinder I chose. I think he threw that in for free too. A+++ WOULD SHOP AGAIN!!!‎
