The Hansen MiniSpinner is an electric spinning wheel. Weighs about four pounds depending on wood...they're made of maple, cherry, and some exotic woods...and the price varies according to the wood.
The base price is $575. ( I think).... the Woolee Winder costs more. It plugs in for electricity...but can also work off a battery pack or car cigarette lighter socket.
It has an on/off foot peddle...not variable speed like a sewing machine...the speed is controlled by a little knob on the spinner. It does S and Z twists.
Totally a wonderful machine!
