Hey,
Thought it might be useful to let people know that I have bought some boards off the guy in Kenilworth's link: http://forums.caves.org/viewtopic.php?f=26&t=18121
I did a bit of digging and mutual contact finding to attempt to verify him and was satisfied that he is a real person and is producing the boards. I had the boards posted to someone in the US who will bring them back later so I don't actually know if they work yet
but they have been delivered and from photos they look the part and includes all the things that you would expect (the board itself, non-mag screws, non-mag battery etc.). I will update as soon as I've converted a disto with them (hopefully in a month or two).
He is charging $370 for the kit. This includes the non-mag batteries which is some consolation but is still a fair amount more than it cost before, and this is before you get import fees and VAT if they are posted to the UK. I had a sort of grant to purchase them and someone in the US to post them to so it was affordable for me but I imagine this might be too much for a lot of people.
I think he was working off a stockpile of the bluetooth chips but he also seems to think he's found a new supplier so it may be a (pricey) option going into the future.
