I second the use of substituting magic items.

You might want to tailor the magic items to ones your group will use, like a flaming axe for a melee warrior. Also try to use more permanent or rechargeable magic items over ones with limited uses by the middle to high levels. For example: an Eternal Wand (Spell Compenidum, Magic of Eberron) of Bull's Strength will go a longer way than potions of the spell, which you won't have to continually give out or create.
