Well, as wizards are wont to do, I'll trade a few of mine for anyone who's got a few high-level divinations to post... I would point out that Perfect Identification is useful in combat. 
PIERCING CLARITY
Divination
Level: Sor/Wiz 8, Clr 8, Intellect 8
Components: V, S, M
Casting Time: 1 action
Range: Personal
Target: You
Duration: 10 minutes/level
This spell gives you an extraordinary mental clarity. You become immune to charm, confusion, domination and stunning effects, and you gain an insight bonus equal to your caster level to Decipher Script, Knowledge, Listen, Search, Sense Motive and Spot checks. (This does not allow you to use a trained-only skill without ranks in it.)
Material components: a clear crystal lens.
PERFECT IDENTIFICATION
Divination
Level: Sor/Wiz 8
Components: V, S, M
Casting Time: 1 standard action
Range: Close (25’+5’/2 levels)
Target: One object/level
Duration: 1 round/level (D)
Saving Throw: See text
Spell Resistance: Object (harmless)
You learn the full properties of magical items in a very short time. You gaze upon an item and, if it fails a Will saving throw, you learn all the item’s properties, including whether it is cursed, how many charges it has, etc. If your check fails and the item is unattended, you may try again the next round. If the item is attended, once it has made a saving throw against the perfect identification you must cast the spell anew to try to identify it (or force the item to become unattended, of course). In either case, you may attempt to identify a different item, but if you return to an unattended item once you’ve moved on to another it counts as another target object.
Perfect identification has no affect on artifacts, and the caster has no way of knowing whether the item is an artifact or is simply of too high a caster level to identify.
Material component: a large pearl of extraordinary value and quality (worth no less than 1000 gp.)
