I am planning on buying my first home theater speaker setup. I have a new onkyo 595 and my current room is about 14x14, but will most likely be a bit larger in the near future.

The package I was planning to get was a pair of M3ti, and a pair of QS4. For the center I was thinking about a vp100 and the the 8" 125 for the sub.

As you can see, I'm on a budget and my living quarters are on the small side.

Question is: Are any of these componants worth upgrading? I was thinking of upgrading to the vp150, but would that be overkill considering my fronts? or should I keep the vp100 and upgrade the fronts to M22s? or since I will be primarily listening to HT, should I get the next model up sub (175 10")?
I cant upgrade too much here, probably only one item. I simply dont know if I should stick with the original plan or go a bit further into debt? Again, I will be listening primarily to HT but not at obscene listening levels (apartment). Thanx for the help!
