I have only been playing for a short while, but I like the Q-workshop designs I have gotten. I am not into all this science stuff, so I cannot account for their perfections or lack there-of, but I really like my Metal Steampunk dice. A nice bit of weight, and a solid sound when they land. Also plenty readable, which is one of my top needs with dice. I also prefer full sets, and won't buy single items like a meteorite d20. I would definitely like a full meteorite set, aside from the fact that it would likely cost 7-800 dollars.
I looked at Artisan Dice, and really like the look of them, but almost all of the dice I looked at have a warning to not roll more than one at a time, and not to roll them on anything hard, because they all chip easily. Cannot justify the cost for a brittle set of dice, as awesome as they look.
The last one I would point out, that no one has mentioned yet, is Skull Splitter dice. I am really wanting one of their sets of Dwarven Dice, more solid metal.
