Coq de Leon is not cheap even in Spain, but it is great stuff for many patterns (I could not live without dry caddis with coq de Leon wings....LOL; deer and goat hair work pretty well...but not the same.)
If you like, have a look at this link, www.pescamosca.com . They are now working on the new catologue for next season, but I think you will find information about prices in Spain.
Hope to be of any help.
