Shame they are all in England!
I don't think transport is that difficult or expensive to arrange. CorrieDhu on here brought Shetlands up from Wales, I think and ours came from Shetland.
If you are in Scotland, contact the SCBA and they'll put you in touch with the Scottish reps. For the North, it's a woman called Paddy Zakaria - I haven't met her but she found us our two heifers last year and is trying to secure a hire bull for us for this year. She's very good.
Demand has been brisk up here - less so in England and Wales. Some of the prices on the website were good, I thought.
