Along with what you have a BCD is a great investment. As other have said you will learn your gear and weighting.
As for the regs and it not "paying for itself"... From a purely financial standpoint you're probably right but diving doesn't make much financial sense sometimes lol. I've spent a LOT of money for the number of dives I've done but the per dive cost diminishes with every dive. There really is something to be said for always diving your own gear.
And I dare say if you're here and asking... you're likely to get you money's worth out of your own gear
