I do like the Picasso II. I have one in an A4000 that I am thinking of selling soon. The only drawback is that it is Zorro II speed. It would be perfect for an A2000 with 3.1 ROMs and an accelerator. A SD/FF card would likely work well with a Picasso II since they don't compete for slots (or even for space) and the Picasso will automatically switch between RTG mode and native passthrough (VGA in).
I hope that made sense, I am very tired!
