is there any messiah 3
 

i went to buy a ps2 and the man there told me that he had a messiah 3 installed in ps2 he was selling is it true??

nope, either you misunderstood magic3 for messiah3, or its a clone( a unofficial copy of another Chip, possibly the messiah2 ).

AFAIK theres a new version of the messiah2 coming soon that also supports V9 Playstations - but still called messiah2.

yeah some guy told me he would install me messiah 4 and I said there is no m4 and he said... well yeah but u don't know until u open the ps2??? and then what I did was just walked away from that store...(I think he used NH4)

Good move.

they got Magic4 - Magic5 - Messiah2 and Messiah3.1 (yes not 3, but 3.1) LOL.... obviously they are all clones
