Two copies is the point where you actually start getting a return on your investment. Not sure how it should be costed. Or if it should be red or blue.
Unfortunately this one doesn't quite work as worded... it allows for the copying of creatures, enchantments and artifacts spells, which vanish as soon as they move off the stack. You have to specify instant and/or sorcery, at least.
Additionally, every existing Fork variant has the conditional "You may choose new targets for the copy", because a copied spell's target may be invalid when the copy resolves (i.e. two 'destroy target creature' effects on the stack, only one of them does anything).
So! You might actually be able to get away with limiting it to one spell type, and reducing the casting cost (due to the potential drawback of copies having no valid targets upon resolution).
i.e. "Copy target sorcery spell twice." for lower cost.
