Hobie seem to be the only manufacturer that prices it's parts list online Europe (in english!) the cost for a Tiger front crossbeam is over £1000, that's probably the complete assembly but then even the tiller crossbar is £200.

edit: Hobie UK Parts

I have seen N6.0 beams being advertised second hand at about £200 each from when I was looking for some for mine. But then we are comparing new for new here.
