I don't know if this is any help to anyone, but there does not seem to be a shortage of the DM10 Pro kit in the UK (I get the impression most people here are in the US?).
If you really can't wait and would pay the extra delivery, perhaps importing from the UK is an option? Also, from what I've read, I think they are cheaper over here. I've seen them as low as £829, and given the current GBP / Dollar exchange rate you may get a better deal by importing???
Google Alesis DM10 .co.uk and see what you find. If you have no luck, let me know and (if its not against forum rules) I'll post some URL's to UK retailers that have the kit in stock.
