Extending Sky cable.

Hi, i'm wanting to reposition my current tv along with my standard sky box ect, to another part of the room, in readiness for my not yet bought plasma, the tv needs to be moved approx 6m from it's current position, anyone know what/where to buy a cheap but effective cable kit?

This is only going to be short term as soon i will be buying a plasma, which i will be wall mounting above the current tv's new location, i will then also purchase sky hd, so sky will be installing new cable run, hence the need for a cheap solution, if there is one?

Thanks.
