I've got a PII in my A2000D and it works great. I also have a Microway FF/SD, to scandouble the anative Amiga output, which I then pass through the PII. I fibd it to be very good. I've also used the board in my A3000D and it wors well.
However in my A4000D I have a C6V4-3D card with scandoubler and its much better than the PII. It did however cost a whole shed more than PII, which I picked up for around $55 on eBay. The CV64-3D cost me at least double that and the scandoubler was an arm and a leg.
In my opinion the PII is a good card but is better suited to the A2000D as its a Zorro II board. For the A4000D/T I think you're better off with a Zorro III board like the CV64 or CV 64-3D (Zorro II and III) or PIV (Zorro II and III). There are others as well like the GVP EGS Spectrum you could consider.
