THe cheaper way is to FILTER air.
Millipore makes filters that take compressed air and block the passage of nitrogen.
So you have two tanks, one is pressured by a regular air compressor, the other is
enriched "air" with a good concentration of oxygen.  This is used as a commercial
source for glass blowing, and other cottage industries.

Compressing oxygen is dangerous, and you WILL raise the temperature in the process,
you will have to add refrigeration!  The rest of the question is just like asking how much water can I
store in a jar.  Think about it!
