This is a great thread, thanks! Looks like that was a great GB, do these kinds happen anymore or is it just basically ordering all the parts from a website?
If there's enough interest there might be a second GB, although I gather that the above GB hasn't actually finished yet, they are still waiting for some of the parts.
You could post in that thread and just ask what the possibility is of joining.
Also some people tend to over-commit on group buys, and then want to sell their purchase before the GB has finished. You might be able to take over someone's order.
