Thanks for that Tony - really helpful! Will do my investigations and see what turns up. It was, in fact, shipping costs that prevented me from sticking my oar in on the sway bar group buy - shipping costs and import duty could negate any savings made.
That said, it sounds like you've got a few contacts in the business - if this gets off the ground then I may get in touch with those guys you mentioned and see what comes out of it!

Thanks again mate - really helpful stuff.
