Haven't read all the posts as my DH wants to check the tide tables....
All I can say is I pay $80 to refill my oxygen bottle think it's a K bottle (44lbs Oxygen) and I have to pick it up! (Actually my DH picks it up it outweighs me by about 40 lbs!) so to those of you that pay $5 or $15 hissssssss!!!! It lasts 20 -24 hours with a minor torch....
I started on a hot head, my husband stole that to weld with works great for outdoor plumbing repairs,
I have a minor on a concentrtor and one on bottled O2 they both get used big encased beads and BU get real Oxygen, everything else gets the concentrator, some things like hollows work better with the concentrator...
That is my two bits!
