I guess it's just rotten luck that discovered Shapeways too late to order some of dizingof's dice. If the D22 parachute die would have been available a month ago, I definitely would have ordered one (saw them on Kevin Cook's website).
I get the point about slimming inventory to avoid overwhelming people. If I found that to be an effective strategy to showcase my top-selling models, I might open a second store on Shapeways that was completely separate for everything else. You never know when a dice enthusiast will come along and you'll make a random sale. (I am right that having a store on Shapeways costs nothing, right?)
Anyway, I thought I'd chime in with my perspective as a consumer. (I collect dice, but it's a casual collection... I'm not looking to rake in mass quantities of dice as quickly as possible. I simply use a little of my disposable income to buy a couple of interesting or unique ones from time to time.)
In any case, fabulous designs and great work, dizingof!
