One great company offering great sound and reasonable prices would be Paradigm. Looking at the Cerwin Vega's, I don't know why you'd want two towers AND a sub. You can use two satellites left and right, and get a better sub that'll go deeper than 32hz.
What would I do?
Using Paradigms for the satellites and center, I'd then go with an HSU VTF-2 ($500.00) as the sub.
Actually, when you say home stereo, that means 2 speakers (for left and right), and a sub... The ones you posted look like Home theater, which requires the center speaker and rear satellites (thus thinning out you budget for any one particular item).
For STEREO, you could get the HSU sub, and two Paradigm Mini-Monitors, be well under $1K and have a FANTASTIC SOUNDING setup. Or, instead of the HSU get a Paradigm PDR-12 Sub (or one of their other models).
