Actually, I would say you are significantly underpowered at the lower levels.
A 7th level MT throws a magic missile for 2d4+2 damage to one target. His buddy the 7th level wizard throws a fireball for 7d6 damage to six targets.
A 7th level MT casts a cure moderate wounds for 2d8+4 points healed. His buddy the 7th level cleric casts a cure serious wounds for 4d8+7 points healed.
A 9th level MT can cast fireball and fly. A 9th level wizard can cast cone of cold and teleport. A 9th level MT can cast cure disease and remove curse. A 9th level cleric can cast flame strike and raise dead.
An 11th level MT can cast stoneskin and polymorph other. An 11th level wizard can cast chain lightning and disentegrate. An 11th level MT can cast cure critical wounds and restoration. An 11th level cleric can cast heal and blade barrier.
The class isn't quite as bad at the even-numbered levels, because they're only one spell level behind pure casters at that point. But they're always three caster levels lower, which means less damage, shorter duration, harder time dispelling, easier time being dispelled, lower spell capacity in each class, and either one or two spell levels behind a pure caster.
In exchange for this, they get a great deal of versatility. But as someone in the other Theurge topic said, at the lower levels, for this class, versatility just means more ways to suck.
The only point at which this class might be unbalanced is at the very high levels - but even then, the three lost caster levels shouldn't be underestimated.
And of course, at epic levels the class becomes a real problem.
Personally, I wouldn't ever play this class unless the campaign was starting at really high or epic levels. In a campaign that starts up from first level, IMO it just wouldn't be worth sucking so badly for so long just to get a (questionable) power boost at the end.
