I have a 1 month old Radeon 9800 pro Mac Edition (128 mb AGP 4X/2X - works in G4s with agp and G5s) for $150 delivered in US. It has dvi and s-video out. Comes with retail box, software cd, manuals and s-video to composite connector, dvi to vga connector and s-video cable. Contact - rayhill2 at mac dot com pm me here
*Please note: This is not a flashed pc card. Also, it does not have an adc connector. It does have dvi, vga and s-video connectors.
ps - this has been a good card but I've bought the 256 mb G5 only card.
