Who is happy with their 4JX1

Okay, just out of curiosity, I am interested to see how many owners of the 4JX1, like me, are happy with their unit.

Also have you had major dramas?? By this I mean big $$$ (injectors, RPS, looms, heads etc). If you have can you elabourate??

Just trying to get an indication of how many units are out there vs ones with probs...
