Question about copying ps2 - new at this

[kiskie]

What is the best program to copy(write protected and not write protected) ps2 games.
Some say CloneCD for ps2. I remember they had ps copy software for ps1, so Im curious is there a special software to use for the ps2 games, or do I just use the clone cd?
Would I also need the the Mod chip to be able to use the games? Where's a good site to get a Mod chip. I'd really appreciate any help. Thanks.
