I have a Creative Inspire 6.1 sound system for sale, it has served me very well for the last 2 years but recently replaced it with a stupid expensive one that i probably wont use as much.........http://www.digit-life.com/articles2/inspire6700/index.html
<----Link to details about it.
Very good quality and i really thought it was brilliant for films and games when i played them on my PC. You obviously need a compatible sound card to use this, but honestly i really rated it.
Shipment costs are dependent on location. If you are interested i will PM you with delivery costs.
