Handing out Magic Items

[Lord Twig]

I have a group that is experienced enough that I want to start introducing magic items in their treasure (besides just potions). Or more likely, magic items being used by their opponents that they can loot off their bodies. The question is, what to give them?

Weapons with +1 to Dx or damage is pretty obvious, and armor and/or shields that absorbs an extra hit. Power stones for Wizards. But what is something more interesting but still not too powerful? I am looking at a Blur ring, which is pretty cheap (relatively speaking, at $3,000) but really seems super effective. So what items do you usually give out, or receive first? What comes later?
