I guessing that the $1500 is for the entire speaker system, not just the two front main speakers, right?
If so, here's my suggestion.
Return the 1400 and get your $799 back. Then buy the same model for $529 as suggested. That puts $270 into your speaker budget.
Now you've got $1770 for speakers.
MAINS - M22ti
CENTER - VP150
SURROUNDS - QS8
SUB - Hsu STF-2
This puts you at $1620. That leaves you $150 to put towards some speaker wire, and interconnects. You may even have enough left for a DVD or two.
Your room isn't that large, so the M22ti's with the Hsu sub should work extremely well for you. The M60's would work as well also, but they do like a little more room, and they'd blow your budget. You'll be very, very happy with the M22ti's and the Hsu sub.
Where are you located? I'm guessing the SoCal area, as you went to The Good Guys. I'm in LA if you'd like to hear some Axioms in person before purchasing.
