Ordered from Christian @ PremiProduct (EBay) he's got one left in stock as there were 2 remaining after I purchased mine. Benefits is not having to pay a deposit. You just claim one and then pay once it arrives in stock. As for waiting a few months later...I can do that
I'm sure I'll have pieces coming out of my ears next year!
good thing about that is if I can find it cheaper elsewhere in the meantime then I'm not committed and can just cancel my existing order. At least I have one claimed if an ES does becoming known in the future
