I saw this as well last Saturday Mike, and I thought the same, I'm not a big volume user of gas, but regular and so the rental for Argoshield, Oxy, Acetylene really bites.
I'm with you, buy the bottle, and its done and dusted and a fraction of the price after 2 years with just gas cost.
We have a 1300 Ltr LPG bullet at home which I paid $300 for 15 years ago, and $170 to have tested about 5 years ago, its paid for itself 10 fold as the rental is now $300 per year and I also get the choice of who I buy from, not locked in to the renters gas.
