Yeah I didn't notice those were in store only. Still have them for that price though.
Lots of brands have synced on/off capability if you buy more than one component in their brand. While it IS a convenience feature, it's really more of a gimmick to get you to buy more of their brand. Lot's of universal remotes, including ones for under $20, can be programmed to do the same thing.
I'm not a big fan of boxed HT speaker/receiver sets, but if you must go that route, there's one with a Denon receiver and Boston Acoustic speakers that's pretty good. It uses the same receiver Denon sells as their entry level stand alone unit. It depends on budget and the space you have, but if you buy in the 2 or 3 months after the Superbowl, you can get decent receivers for $150 and add a speaker set for $400 - $600 total price.
Whatever you do, don't assume the better name brands have decent sounding HTiB speaker sets, by that I mean the speaker sets by themselves. For instance Definitive Technology makes some decent high end speakers, but a lot of their HTiB speaker sets aren't anywhere near worth what they're charging, like the ProCinema 400 that goes for $600. You'd actually be better off with the Denon/Boston Acoustics set that includes receiver for about the same MSRP, but way less street price. http://www.amazon.com/Denon-DHT-1312BA-Receiver-Acoustics-Surround/dp/B004U40598
