I'm personally not going to use this rarity system in my campaign. I will take it into account as to what I dispense out, perhaps, but as we can set what's available to buy and the enchant magic item is limited to the ritual user's level or less, I think there's some pretty good safeguards in place (aside from limited gold, no less).
I think these needlessly complicate the game and cage in the players more than I am comfortable with. I don't hand out a lot of gold, so I want them to be able to make the best of it and feel like it's truly valuable.
Forcing them to either buy junk they don't want or hold onto their gold certainly controls the power level of the players better, but it doesn't do any favors for the fun of the game and the excitement level of being rewarded for your efforts.
