I don't get it. Even 250EUR is cheap for this! I'd easily pay 500-600 USD for the A4000 version. Mainly because trying to get any Cyberstorm is going to cost 700-1000, and it could blow up a week after you get it.
While sure I could understand being annoyed when you were told it'd cost half that, then suddenly the demand is too high so it doubles. Do people not understand supply/demand? Hell, I'd donate to keep kipper building stuff, I know I've ordered something from him (I think it was the PSX to DB9 adapters that I use all the time on my Falcon now).
I really want that A4000 Vampire though..
