Well, the board itself is sort of standard-hardware.
It is a question of money to have a new production run.
Don't ask me how much money, though.
Refer to
http://homepages.picknowl.com.au/sirius/phoenix.htm as mentioned earlier, but be ready to deal with Andrew... he can be slow at times. Reminds me of a weird professor at times: a genius at work, but unablbe to use all these numbered buttons on this telephone-thingy

.
The 50 new boards were made because of the estimated numbers of buyers from Germany. We made a project out of it, and as one result, a1k.org was born. Please be aware that we paid in advance. On the other hand, it was the only new Amiga-classic-motherboard since the demise of Escom. And yes, they were newly made for us.
I think it's worth it. Also be aware that only some chips are available. The custom chips still need to come from some old amiga, and afaik Andrew works on some mods to some chips to allow for example mor than one type of Agnus for 2MB Chip setup.
Did that answer some questions? Do you have more?
Have fun,
