Which do you guys think would be the better set up? Im looking at spending under $999.99

Speakers and receiver. But it looks like with this set up Im going to be a bit over budget
1. I was looking at the SVS SBS-01 set up for $799. Is the 12" sub for $100 more worth it? or should I just spend that money on the receiver?
2. Is there a Receiver for around $250-$350 that will run these with at least 7.1? I dont mind open box or refurbished. Also if I buy a 7.1 Receiver will it be impossible to ever run 2 subs?
3. Will this be the best value for my money? Or should I piece together a system? I tried looking locally to see if anyone around here sells these but I didint have any luck. I wanted to hear these to make sure they were good for music as well as my home theater.
4. One last question....If/when I buy these and down the line I decide I want more.....what would be a good set of towers I could buy to complement these and turn them into a 7.1 setup?
Thanks for any help or advice!!!
