I just picked up one of these http://www.thewarehouse.co.nz/red/catalog/product/Teac-2.1-Channel-Soundbar-with-Wireless-2.4Ghz-Active-Subwoofer-LSB200SW?SKU=1599636
from the Warehouse in Albany - $99 Manager Special - but if you ask nicely you can get another $10 off. Seriously good replacement for my PC speakers - will try them on the Kitchen TV tonight.
Be quick not sure how long on for.
