Ok, let's make my question simple.

Considering the price, I can accept the M3 or M22 to build my stereo system for now. I choose M3 because my room is less than 200 sq.ft.

I can also put about $400 more on speakers if I can get real approach to HT effect. That means I can choose from surrounds+center, another bookselves+center, or what you recommend ? Since any combination with subwoofer will exceed my current burget, does a subwoofer only help anything here ?

If the burget is too limited for a 'home theater', I may save it for a few months until I get enough to build the whole system. The stereo system is my major consideration. I just want to know if it's worthy to put the extra money if I cannot get the entire solution for a period.

Thanks for any input.
