Merlins are really rare. Most of them are in Europe. Mine came from Finland. It is a much better card than the Retina Z2 in principle but it has a few issues. It needs a couple of hardware fixes to work with gvp accelerators and 060 processors which are still available for a mere 20 euros. It works beautifully with Picasso 96 drivers. There is also a native RTG system called ProBench but the full version of this system is severly copy protected and the software will only work with the Merlin card it is licesnsed to. There is a demo version of Probench 3.9 that only works in 800x600 that I've gotten to work and it is about as good as Cybergfx--it can do Deluxe Paint in RTG modes! Picasso 96 can't do this trick.
And the best thing about my Merlin is that it came with the video ecoder board which converts native Amiga modes into composite and S-Video and spares me the outrageous cost of a flicker fixer for my A4000. It does this at the hardware level and no drivers need be installed for this. :-)
