Clint, I like to grind my larger grains (1/8" to 1/4" max.) of pink salt at the last minute as a finishing salt, not so much for the flavor, but for the salty, crunchy texture that gives a little surprise and burst of saltiness when biting into the food.
I just bought my first Maldon sea salt and the crystals are quite flaky and quite large but not as large as the pink salt from Costco. I bought a mill too (
Oxo Lua), which is larger than their other model and which received good reviews) for the pink salt but think I'll sprinkle the Maldon by pinches. The Oxo Lua also has a matching pepper mill, but I can't speak for that one, one way or the other.
BTW, Bed, Bath & Beyond carries the Oxo mill too, so if you have a BBB coupon you'll get either $5 or 20% off. If you go to a BBB store, I'd suggest you try to test the grind on several of the same model. (They come partially filled with salt.) I have mine on the coarsest setting and it is all right. A couple of others that I tried at that setting did not grind quite as coarsely, and were not as coarse as I was looking for.
Anyone grind their Maldon?
