PS2 Modchips are becoming rare items right now owing to the legal action being taken by Sony. For what my opinion is worth, if you can find a #####r with NEO 2.5 or NEO2.2, get that whacked in quick smart. The only thing it won't do is direct boot backups or import originals; the former remains a swap process and the latter the same after you've CloneCD copied it or PrimoDVD'd it.

You won't find a Messiah anywhere; nor NEO4 and Origa supplies have dried up so far as I know.
