The CO2 distributers around my area are only opened on M-F from 7am -4pm, and refll on the spot, and 1 day turnaround for Hydrotesting a cylinder. To give you an idea of prices:
A 10lb reconditioned (used) typically costs around $65-80 filled and tested.
A 5lb reconditioned costs $50.
A refilling costs $10-15.
You might want to call around for the best deal. I think you are getting food grade CO2 gas which is a little more expensive then Industrial grade. No real difference for aquariums, but the industrial grade is less pure (metals) then the food grade. See if you can find anything else in the yellow pages, internet for Fire Supply Extinquisher Shops, or Welding Companies.
Another option, you can call ahead to the place, and see if they can swap Filled and Empty cylinders on the spot, so there is no lag time between days when CO2 runs out.
