Yes, the Pioneer Speakers have been my go to for budget recommendations for a while. Best Buy used to have a 5.0 package for ~$360 if memory serves, and Newegg regularly has the BS21s at $50 per pair and the BS41s at $99/pair.
Couple these with a modestly priced subwoofer and you have a great entry level system. Or, step up to something like the Outlaw LFM1-EX, the SVS PB12-NSD, or the HSU VTF-3 and you can have a great $1000 system.
