I can't be the only saddo with a soft spot for this. I really, really miss it despite my deep-seated (and I suspect not entirely misplaced) fear and mistrust of small rural communities.
They have it on Play for £17.99 inc delivery. Amazon have it for the same price but you would have to pay delivery or make it up to the minimum order for free delivery.
Series 3 is already out for Region 1, they have it on CD-wow but it only comes with the fluffy jacket and cost £9 more than the UK region sans fluffy jacket so I'm going to wait for it to be released over here. It shouldn't be too much trouble to wait, I just don't get the time to watch anything any more so it'll probably take me about 3 months to get through season 2.
