I followed the same schedule as N2DeepInAz. We dive several times a month, but I was finding myself renting tanks and then not going, or waking up Sunday and really wanting to dive but with no way to get tanks. Make sure and let your LDS know you are interested in tanks, we ended up with a pair that had been used twice for a pretty good discount. My trigger point was when we were diving enough that the difference in rentals ($8) vs refills ($5) was enough to pay for the tanks in 2 years.
