We have just contracted with Westminter Carpets for fitting of Amtico. I think there are cheaper Karndean options, but Amtico is two price brackets either 42 or 70! per square meter roughly. The higher end Karndean we were considering (as against the lower end Amtico) was ?10 per square meter cheaper for the tiles but as the fixed costs for screeding and fitting are the same for both, the overall differential in price was not significant, so we went for the Amtico. They did say there is little difference in quality - we just preferred one of the Amtico choices which was in the ?42 range.
