mucker:
just do as haymigga told you , go for an MEDIATOR ZorroIv solution and add an Voodoo3 card ...its blazing fast compared to aga and even compared to BPPC with bvision.
though one catch, it does cost abit..
if you dont have much money, then go for an Cybervision 643d card, should be fairly cheap on ebay theese days , this u connect to your Ziv , sadly speed will be a problem but maybe enough for you while you wait for an amigaone.
cheers
