Help me out with this...

[ht_skinny]

I live in an apartment right now so I can not have a HUGE BOOMING system as I want. so I was thinking of getting a HTiB but I have read many bad things about them, so I guess I just have a few questions. I will be getting a house sometime at the end of 2009 so a finished home theater basement _will be_ in the works. I am alo on a lil bit of a budget that's why I was thinking HTiB or buying equipment in pieces. Anyway...

1. If I were to buy say the Onkyo HT5100 I believe, it's a 7.1 system. Now, the receiver that would come with this, would I be able to buy better speakers down the road and still hook it up to that receiver?

2. Does anyone know what receiver actually comes with this system?

3. Or should I go with this idea of buying the Onkyo SR 606 or better, then buying the speakers as I go along? Center first then left and rights and so on?

4. If I go with this, can I have the Onkyo set up with say just the center speaker and still get sound or do I need at least the front L,R,C and sub?

Sorry, I am new and just trying to figure out somethings before I go spend.
