Quickened Spells in Magic Items

[Sudden Deinonychus]

Just looking for confirmation of something, and if I'm wrong, please correct me. If an item is created that has spells, such as a ring made to cast fireball 3 times a day, something like that, but that spell is Quickened, I'm a little unclear on how that would work.

My guess is that since the ring would, in this case, be word or use activated, that it's a standard action to use it, so the fact that the Fireball is Quickened is completely irrelevant, as a standard action gets used anyway. Am I correct?

Non standard item requires the GM to make the ruling ... so it does whatever the GM allows which could include firing off a Quickened Fireball.

Or (bolding mine)

Activating a magic item is a standard action unless the item description indicates otherwise. However, the casting time of a spell is the time required to activate the same power in an item, regardless of the type of magic item, unless the item description specifically states otherwise.

The above continues on with describing the 4 ways to activate a magic item and further details about each method.

If you were able to make an item which was a swift action to activate via quicken spell you'd change the spell level to the quickened one and change the minimum caster level to that which the quickened spell level required.

E.g. If your standard action fireball item cost 3 (spell level) * 5 (minimum caster level) * 1800 gp say for a total of 27 000 gp, then a swift action fireball item might cost 7 (spell level 3 + 4 for quicken) * 13 (min'm CL for spell level 7) * 1800 gp = 163 800 gp. 3 uses/day would reduce that by 40% but it's still a lot.
