Quick summary: Just bought first house, need a home theatre, bought an Onkyo TX-SR607. I wanted to go the full 7.2 route, but after looking at some of the axiom stuff and deciding I want it (plus custom wood/finish? SWEET!), it just doesn't seem to be in the budget to buy it all at once.

Easiest way to put this is: If I'm going to piece it together 1 or 2 things at a time. Which order should I be buying things in? The order I was considering (by product) was:
2xM80
1xVP150
1xEP125
2xQS8
2xQS8
1xEP125

Thanks for any thoughts/opinions!
