Sure, I have five or six orange Paris Expedition sleds sitting in a shipping container in Punta Arenas, Chile. I guess that's not helpful?
Then again, for the prices on that Aiguille page for their kit, personally I'd prefer to fly to Chile. Paris XPD sleds are around US$30 in Tru-Valu hardware stores in the US.
Have you gone onto some of the Facebook groups for polar expedition stuff? I can't believe there's not quite a few suitable plastic sleds about in the EU/UK.
