So I called Quality Light Metric in Hollywood to ask if they can get me the spare dials and perhaps calibrate the SinarSix. It turns out that they have no idea what my light meter even is and, that said, they can't get the spare dials or even calibrate it.

I guess the next step is to either buy a used SinarSix with all the dials from eBay or just get a whole new kind of light meter/spot meter altogether.

What do you guys suggest I do? I do like the concept of how the SinarSix works, especially since it also apparently takes care of bellows extension.

I guess what I'm asking is should I just get a whole new SinarSix, or should I get a Minolta/Pentax/Sekonic spot meter?

I'm afraid of constantly using my iPhone app. It's good for what it is, but I think that, sooner or later, it's going to screw me up.
