To answer a few people from a few threads that I didn't want to hijack:

Yes, I will be bringing buttons to Amersfoort for the meet. They will be sold at a slight discount from the web price. And, you'll save shipping cost, currency conversion cost, and won't have to wait for the package to arrive. (and it'll be less work for me because, phew, I was up till 3:30am last night packing orders... though I only started at 11pm).

I was hoping to create some special custom modified buttons especially for the meet, but I have to reclaim my Dremel tool. We'll see...
