You might look at Wharfedale, Polk does have a new line of affordable speakers that are supposed to be good for the money, possibly Infinity, or Elac.

You sub suggestion will work and give you more flexibility as far as adjusting bass for taste, but the down side it's sometimes tricky to get the sub to blend, or sound seamless with the satelites.

I'm not sure what your integrated budget is but Jolida did have a respectable 100 wpc hybrid for around $550.00.
