You could go for the new ACA 1221 accelerator as on
http://amigakit.leamancomputing.com/catalog/product_info.php?products_id=1251 , but they seem to be currently out of stock, or perhaps they're still available on
http://www.vesalia.de , but they may have decided not to mention if they're out of stock. They were on holiday taking pre orders for this card before they came back.
You also need to consider why you want to buy an accelerator. I've recently been exploring the gradient fill options in Deluxe Paint 4.5 on my Amiga A1200 with 2Mb upgrade card in the PCMCIA slot. This is like a basic type of raytracing, with some fairly impressive results.
I hope to transfer my Amiga artwork onto other devices soon, then set up a website of it.
