I  too would like to buy up to 4 X5 boards. As you all may have seen, there price jumped from $500 to $650. I wonder why they are selling these at all at this point. Maybe a new chip nearby? Perhaps I missed it in other comments, but what is the shipping time like? I think the minimum buy is 10 boards if I understand correctly. I asked for clarification, but didn't get a reply from Vadim. What is the total demand from this forum so far? Have they answered anyone regarding weather or not they will use escrow?
