If you want powered monitors, I actually use Yamaha HS80m monitors for my computer speakers. They are actually not bad. There are a couple used on UK Ebay:
Or you can try to find the newer Yamaha HS8 monitors, but will be even more than the Emotivas. Not sure if these will be better than the Emotiva. Emotiva has a lot more power and will probably be more laid back sounding than the Yamaha. The Yamaha are very neutral, but also very revealing. They have a larger 8" woofer so they would play a lot lower than either of the Emotiva monitors.
