prices on HTIBs (Home Theater In a Box.) Often Onkyo is the make with the greatest bang for the buck.
Saying that, I also feel such a convenient solution is a temporary fix for those who grow as a discriminating listener. They will not remain satisfied. HTIBs try to incorporate too much convenience in a package destined to contain some fatal shortcoming.
As a minor audiophile of 45 years standing, along with like minded persons, advocate a quest of permanent quality. Many get entranced with interesting sales hype surrounding receivers. That is putting things backwards. Selecting the speaker(s) most liked for your price point is key as that is where most all the obvious sound difference is. Speaker brands have their own distinctive sound character. What best suits your ears is likely not what I would select for myself.
One can start with just two speakers & add on as money trickles in over time. Power source needs for most are actually rather modest. Receivers have so much more performance & value than they used to be. So, actually one should spend time learning enough to determine their needs & wants in their own A/V setting.
So check out the HTIBs of Onkyo & others offered by places like jr.com.
