speaker recomendations, athena?

I've posted before about going with an onkyo HTIB setup, I decided to go a
component route, I just bought a Denon AVR-686 receiver, I'm looking for
speakers to go with it. I've been looking at the Athena Micra system (5.1)
but want to do a 7.1, anyone know where to get the micra system cheap? (best
I've seen is bestbuy for 283.99, but they are on backorder) can someone
recommend something in that price range? or should I just wait for those?
like I said, I'll be adding 2 speakers to this, was thinking of getting 2
front speakers (possibly athena B1's or B2's) and using the included
speakers in the Micra system for the side and rear surround. is there
somethign else around the price of the B1 that you would recommend instead?
I'm looking for speakers this small ebcuase I already have 4 speakers in teh
wall (OLD bose speakers that are blown, they measure about 3 feet wide and 2
feet tall) so I'm going to take off the grills, and cut a hole in these
speakers and place the new ones inside, then put the grills back on so it
will still look neat) thanks in advance
