Suggestions for side and rear speakers please.

[tacomaprime]

Currently my home theater setup is listed in my signature. Pics will be posted sometime this week. My fronts and center are set, I don't want to change them. However my current side speakers are onkyo fronts from a HTIB system, and my rear speakers are non existant. Due to the setup of the home theater room, I have decided I want to do some flush mount speakers for the sides, and some flush mount speakers in the ceiling for the rears to complete my 7.1 system.

However, I have never had flush mount speakers, so I know nothing about them. Are they as good as regular speakers? What brand is good to go with. I was thinking klipsch if I can find them, but are there speakers that are just as nice for a lower price?

That's another question, where can I buy flush mount speakers?

Thank you for the help, and again I will post pictures sometime this week.
