Now, bear in mind I ordered this a week ago... Not their fault, but for me, I really don't think they should be taking my money without having a firm idea of when it will be delivered. I think a lot of people, informed of a delay of at least a month at point of sale, would try to get it elsewhere. Now going elsewhere seems like a faff since no one else seems to have it in stock either. Looks like I'll have to wait...
Review will be a while coming then.
