Indicators: are the metal ones better?

[jTheUmp]

I seem to be hard on indicators... I find that the clicking mechanism seems to wear out on me rapidly. I've gone through 2 of them this season so far, over the course of about 40 games.

Not a huge deal, since they only cost a $5-6 apiece, I can afford to replace them often, but I'm wondering if they metal ones will last longer then the plastic ones that I've been buying so far (I haven't yet found a local shop that sells the metal ones, but I can get plastic ones from any number of places).

So, what have your experiences been? Are the metal indicators worth the price?
