| I like the statistical occurence of cursed magic items in OD&D Supplement I: Greyhawk:
Wand/Staff/Rod - 0% chance of cursed
Misc. weapon - 3% chance of cursed
Potion - 7% chance of cursed
Scroll - 10% chance of cursed
Armor - 12% chance of cursed
Sword - 16% chance of cursed*
Misc. magic - 35% chance of cursed*
Ring - 48% chance of cursed
Overall - 13% chance of cursed
*plus aligned items that aren't cursed per se but may still have negative effects on characters of other alignments
With these percentages, you'd better bet players will think long and hard before trying on every random "magic ring" they happen across...
