The base B2 is double the price of the B6, at £2100. You do get the little things such as covered BKs, locking tuners, coil-splitting etc included in that though.
I spoke to Doug last night, he explained that he's having major problems with both his internet and email account - he doesn't receive most emails and even then, any replies he writes are returned, having failed to deliver. If you want to get hold of him urgently, I'd highly recommend calling him, even at international rates. He is at Frankfurt for the MusikMesse until Sunday as of today as well, but I'm sure he'll still be reachable by phone.
On a side note, my B2 is 90% ready - just needs electronics and hardware put on, hopefully collect it next week!
