Onkyo the way to go?????

I am looking for a reasonably priced all in one dolby digital 5.1 system (preferably under $300), and have always been partial to onkyo, I found this one at Ciruit City for $269: Onkyo Home Theater System (HT-S590S) Wondering if anyone owns one, or have any insight on which one to choose(doesnt have to be onkyo). For a while I considered that logitech z-5500 5.1 system for $239 as my home theator setup is pc based. Problem is there are very few stores with these units set up, and the ones that do dont have them set up in 5.1. I NEED YOUR HELP

I believe the sub is passive, in which case, I wouldn’t buy it.
