The limiting factor is the PCBs really. I ordered a bunch extra so we are far from there yet. I won't be ordering components for all at the same time though. That would be a lot of money, and I want to start off with a few to see how everything works out. If I get them to work, if other people get them to work, how many are going to drop out, how much hassle other people are going to give me and so on. I will of course add the overshoot to the last batch of components. They don't need to be in multiples of 25, it's more like a minimum to achieve free shipping from the suppliers, as well as a good price break on many of the components.
But I am adding your name to the list for now =)
