"I'm not to sure that a Z2 based gfx card would be a very nice to work with."
It sure is better than AGA when you want to do some serious work. Before I bought Mediator and Voodoo3 I did have ZII busboard and GVP Spectrum GFX-card. I can tell you that even ZII + GFX card makes your Amiga feel like a new computer. If you don't play games so much then even Zii is more or less ok. You get much bigger, more colourful and flicker free screens. It sure is worth it. You can't even dream about using 800x600 256 or 16vit screens if you have just AGA.
Because Zii really is slow when ccompared to ZIII or PCI, then some games seem to run better on AGA than on gfx card+zii bus. But eg. Napalm was much more enjoyable than in the AGA screen.
Ofcourse I would strongly recommend Mediator PCI-busboard instead of ZII or ZIII-busboard, because Mediator is much faster. Eg. Voodoo3 3000 connected to Mediator easily beats PicassoIV + ZIII-bus. Zorro cards are also still expensive, you can connect cheap standard PCI cards to Mediator.
