I think the Peloquin is slightly cheaper than the Quiaffe, and includes a fitting kit (which I think is another £100-odd from Quaiffe - I know - I bought one, but not yet fitted) - as you'll know it's not a cheap mod, and I've never seen a diff much less than £450-£500.
Only hidden cost I'd watch for with shipping one from the US is the customs duty on arrival in the UK..., and not sure that a company like ECS would ship such a thing as a gift (ie, qualifying for zero duty...)
Maybe the best thing is a few wanted ads on a few Dub forums to see if anyone has one unfitted that they now want to offload...
