£40 incl special delivery, they are bloody good.
Should have some black rhodiums, some soniclink, silver sounds which is chord essentially (thats where chord had them manufactured), some SHB avatar tsc's, and some nordost (got some red dawn, blueheaven, tyr, valkyrie) and a few others.
Depends how much u wanna spend, will have to have a nose around later and give u exacts on terminations and lengths.
The silver foils are right next to me thats why I can be more definate, may have some cardas also.
