Salts?

What do you all use for salt. I have only used two salts since i set up my aquarium. I started with Crystal Sea and when I could no longer find it in the stores I switched to Instant Ocean. I always thought that Crystal Sea was a good salt and i never had problems with it.
I am once again out of salt and was looking for Crystal Sea online and found a very very negative review about it. Has anyone else used this salt and thought it was good or should i stick with Instant Ocean?
