I have read here that the cambelt idler tensioners (or their bearings?) should be changed as a matter of course when doing the belts themselves.

Checking the price of these (the whole units), they aren't a small $ item (say AU$1000 fitted) on a 3.2 engine. The Ferrari shop claim that they are pretty robust on the 3.2 and don't generally get replaced, but what opinions can everyone give me? Bearing in mind that if the belts themselves are to be changed every 24 months as per the manual then that is a lot of new tensioners over time.

When I did my cambelt change on my 328, 355 and 360 before, I had the bearings changed. I think when it's done while the cambelt is done then it should not be expensive. Otherwise they'll have to open the engine cover and so on, in the case of the Mondial (transverse engine ?). But in the case of the 355 it's a major job, it would not involve taking down the engine. In any case change it and you can sleep soundly after that.
