Earlier this year I paid £180 for each of three 10m fibre-optic Displayport 1.4 cables. I now find that they're now available for £80. This is competitive with high-end copper cables. (OCUK don't sell these, so not competitor links.)
I can thoroughly recommend fibre-optic cables, and hope they come down in price even further.
