Since I remarked on the durability of Gamescience dice, I do have to say I also find that they are no less pleasant to roll than my other dice (I own plenty), and I don't find the colors unappealing. However, I will say that I do ONLY own blue dice (a few white, black and crystal clear, too), so my dice-buying range is severely limited. Why, you ask, do I own only blue dice? Because once, years and years and years ago, we had a "my dice are all this color" rule at the table of a public game shop. I picked "blue" as my color, and stuck with it. Now, I just find myself reluctant to break the rule.
I find crystal dice to be the most annoying invention. I can't read them from more than 3' away, no matter how well they're marked. So as well as all blue, I try to stick with all-opaque, and all solid-color (none of those speckled or granite dice for me)!
