I also would love to know what the story is, as I spoke to Brian at great length late last year about purchasing a 250 cal kit. I went to Stoneleigh last year specially to see the 250, I even went and got myself a mortgage to pay for the build!! Then suddenly nothing!
I do hope there is a very good reason for this behaviour.
At least, unlike someone here, I didn't go and buy a Z3 (although very nearly)!
On DNA's "new" website there is strangely no phone number, only an info email address. Also DNA have not responded to any threads on DNAOC which is sort of their forum.
