Bluetooth (or Wireless Speakers) Questions

I am one of these old fashioned people who runs a tower base unit and a separate monitor - But I would like to play my music from this PC to others rooms......my thinking was that I would need a bluetooth dongle - and some bluetooth speakers ? .......or could I just get away with Wifi speakers ?

I have a terrible taste in music - so don't want to spend loads......any suggestions...... [uk based poster}

Bluetooth would be the way to go, however I don't know the distance capabilities of Bluetooth. I don't know anything about wi-fi external speakers. There are wireless devices available - you connect the wireless transmitter to the PC's analog sound output and the receiver to the powered speakers. These will work in separate rooms.
