Nilo, another welcome. I'd certainly agree with Randy(sirquack)that you shouldn't delay on the QSs. If the budget is a bit tight, I'd suggest putting off the VP150, since you could use the Onkyo, or even no speaker for a "phantom" center. Using two of your Onkyos for back surrounds, as Gena suggested, is okay, but the QS side surrounds are really better. Your Onkyo receiver is fine for use with the setup.

Enjoy the music, not the equipment.
