First home audio system - HTiB?

[kavkazi]

I have the following setup, and looking to add a home audio system.

Panasonic Viera TC-P50V10 (50" PLasma)
Play Station 3 (used as blu ray player, and gaming)

Budget: Under $1000
Size of room: 24 x 12. Ceiling 9 ft.

After doing some research. The most decent HTIB is the Onkyo HT-S7200. But I can't find any available in Canada. Is there any other comparable HTIB?

All the experts say its better to build a custom system.

I am a newbie, afraid I won't be able to use the reciever to its full potential (i.e. setup etc). Is the HTIB easier to use?

Any suggestion on what would be the best option for me for under $1000?

Thanks in advance.
