I can heartily recommend going down the Mediator route now mine's working ok... but it was a long and frustrating road. As the others have said, it can be a frustrating item to set up correctly even if you follow the many guides and wikis fully and especially if you're trying to add it to an already established amigaos installation. In my case a rogue LoadModule entry which I missed, and a not directly related but corresponding hardware issue, caused many weeks of head scratching and I came close to selling the lot. All that said... now it works it's great, it's more powerful and (possibly) cheaper than going down the Picasso IV/CV64 + rapidroad/x-surf100 route.
As one who's paid through the nose (twice) for a G3 Sonnet.... well, it might be madness but it is a fantastic upgrade and will only get better as the driver matures. Who knows what's next - may ifusion and OS4?
