First of all you need to identify your ps2, check this page to see how:

Then you must know that crap like Neo will destroy your ps2 laser and need the swap method..So I suggest you to go for a Messiah, which is swap free for all kind of backups, but only work with Pal ps2 or Usa V4(If I'm not wrong)..If your ps2 isn't compatible with this one buy the origa(similar to messiah,but need a swap for dvd backups).If you're interested about those 2 mods mail dust2dust or charlie_ps2 for more info and prices
