Bargain at about $20 including shipping, cheapest on shopbot is $30 for one (http://www.shopbot.com.au/m/?m=jackson+POWERHAND). The site description:
A unique powerboard design substituting the usual strip for a series of short leads. These leads allow power to be availabe to all sockets, even when bulky plugpacks are used which would cover adjacent sockets on traditional strip design powerboards
Freight was $11.71 for me. Too much for a $10 product.
