Where is "around you"?
The Infinities when on sale are near impossible to beat for the same money. The only thing I ever saw that beat them was the DCM's when they were being closed out!
I would go with Infinities for the front three - be sure to get the RC-263 center as it is very much worth the extra money! Use the Paradigm mini-monitors for your surrounds, I really liked them for what they cost.
Are you sure they are on sale? Usually they are sold by Infinity/Harman at better than 50% discount and would show up here!
