I would use some variant of my house rules for buying magic items: http://www.enworld.org/forum/showthread.php?404489-Buying-Magic-Items
Ditto for the "ingredients" of the formula.
I'd make the formula require one ingredient per "yes" answer to these questions:
- Would having this item solve too many of the PC's problems, making the game boring?
- Is the effect so unique that it would alter the setting if these items were easy to make?
- Does the item just seem noticably better than other items of the same rarity?
