I still get it from Minneapolis Oxygen Company...
@kimrin...it really depends....they have sales every now and then...
I just happened to walk into one a few months ago....and upgraded my 10lb to a 20lb at a kickass price...
the main thing is gonna be....which size tank you are gonna purchase...
which is a one time high initial cost....depending on size...
after that the refill is between 9 -12bucks..
so there aint gonna be that much difference..."refilling" a 5-10-or 20 lol
and ofcourse...the first time you buy the cylinder...the first fill is free
