Most expensive item in Oblivion>

[Dash]

I was just wondering what the most expensive thing in the game was, thought it would be fun to see ow much it was...

As far as standard items, a quick glance at the inventory for one of my complete-freak characters says Daedric Cuirass is the most expensive armour (4800 gold list price) and Daedric Warhammer is the most expensive weapon (5000 gold). As for enchanted items, the most expensive thing I've found so far is the Mundane Ring (list price a whopping 21600 gold) but there could be other items that are even more expensive that I haven't found yet.

What exactly does the Mundane Ring do and is it available in the 360 version or only through a mod?

Mundane Ring has reflect spell 35% and resist magic 50%. Not exactly "mundane" in my book Available in stock Oblivion on all platforms (no mods required). It's available as random leveled loot from some high-level NPCs, but only one static location (SPOILER: If you're level 22 or higher when you do the main quest mission "Camoran's Paradise", Raven Camoran will have one).
