Hi
Problems with scooter and cave is to think about kicking back.
So if you only get one, as Tbone said, they are "conveniences".
If you want to go further than kicking distance you need extra gas or/and another scooter. So extra budget.
And then, when the gas becomes a problem, the next point is getting a rebreather. So extra extra budget.
But then, you can get longer dives and need top of the range machine like the Genesis but at this level, you need two of them...
extra extra extra budget
So for the OP, if you have the money it is fine for you to get any dpv you like but even with plenty of money, don't shortcut experience.
