Glad to be of help, Nuntius.
And I'd second StreamOfTheSky's assessment of balance and usability, on most points. I don't think Beguiler and Duskblade are too powerful, but Beguiler at least definitely steps on a few skillmonkey toes.
But then again, full casters are used to stepping on everybody's toes, and Beguilers, Warmage, and Dread Necromancers do a better job of letting others have a little screen time at high levels.
Also, I want to say that Binders are one of my favorite base classes. I'd play one even 1-20, with no multiclassing. I'd just have to wrap my brain around all the vestiges first... (only got my Tome of Magic recently).
