Neo4R Euro Pal for v5

[aero]

I'm thinking about buying a mod-chip in the next weeks.

I found the NEO4R chip at lik-sang
http://www.lik-sang.com/catalog/prod...ducts_id=1843&

for my v5 ps2. It seems to be better than messiah, because you can play any dvd region with it. Or is there sth. negative I have to know (No Imports or difficult installation or sth. ...) ???
