I was interested in this... Then I looked at the price. 229€. What.
I know it's bad form to criticise Amiga HW prices, but this one takes the cake. You can read in this same thread that the Cirrus Logic chips used are sold for cheap, so I can't fathom where such a high price is coming from - especially considering that there wasn't much software development needed at all, as it reuses pre-existing P96 drivers.
