Spoke to Bourke at MacDev this evening.
The regs for use by us in the UK have to machined slightly differently (so they can use HSE bottles) and they are next on their machines. He said realistically it's going to be 2 weeks before they are machines and packaged ready.
They are also producing the PI bottles to go with the regs which will use their own standard of fitting (I'm not exactly sure what the differences are) and they should also be ready around the 30th.
They are also talking to a UK dealer at the moment with regards to becoming a proper UK outlet for them but I can't say who yet as details haven't been finalised. So hopefully, in the coming months it will be a lot easier to get the kit in the UK
