If they are Wilbers springs in a different box then �79 is a good price.

Personally, after having tried progressive and linear springs back to back, I don't rate progressives. Linear springs offer a much more compliant and controllable ride and are far easier to set up in terms of sag and damping. The Ohlins 6.0N linear springs are well worth the �20 extra IMHO.

See here for my experiences with both types of spring.
