Save? Flip? Buy on a whim?

[Sufler]

This is a discussion my friend and I had recently. Out of curiosity, we were wondering the process a Rolex enthusiast takes to acquire new models. Do you save up? Do you flip one to get another? Or, do you usually have enough discretionary income to be able to buy what you like on a whim? After all, some of you guys are professional Rolex buyers.

Thanks!
