Roll Bar

I want a Hard Dog Roll Bar for my Mk1 Mx-5 but i live in the UK (Yorkshire) and there arent many for sale, there is one on eBay but it is too far away and the seller hasnt replied to my question about getting a courier to pick it up, insinuating that they dont want to wait in for a courier. Does anyone know where to get one or have one that they want to get rid of (one that will fit with a hardtop, preferably the m2 sport)
