-chuckles- Yeah, but I have 33 ranks in Disable Device. 
Cloistered Cleric of Wee Jas 3/Wizard 3/Mystic Theurge 10/Dread Necromancer 14 avoids most of the pitfalls. Just gotta take the -3 spellcasting levels on the chin to accept being useful all day 'round. (Was it Dread Necromancer or True Necromancer? Damn, it's been too long since I played. The one that's like Mystic Theurge, only for Necromancers...)
One thing I'm gonna love about 4E: Playing a Wizard who never runs out of spells. Or, rather than using that needlessly complex build, taking a Cleric Training feat.
