Does anyone know a decent Alfa Specialist in Dublin

[bmcgran]

I have a 2 litre 156... the timing belt was changed in January....
now the car has developed a slight mis-fire, Airton Motors (Alfa dealership) have said they want to change the belt again just to be sure, even though they haven't noticed the mis-fire since I dropped it into them this morning!!

Can't help feeling that there must be somebody in Dublin who knows what they are doing with Alfa's and it probably isn't these guys.

Any ideas of who I can turn to?
