It's not powered but it's so cute - the Macally 4 port hub for notebooks. I use it on my G4 tower so I use an extension usb that plugs into my other hub because I wanted the USB ports near me. The hub is white but when plugged in it has a blue LED glow inside!
How about a brand new 4-port hub with AC adapter for $14? If you are in Toronto, you can get one here . Canada Computers is generally a good place to look for cheap PC parts, if you ever need anything else. Hope this helps!
