This is probably roughly what the market would support for these cards. Before the S5 came out the S3s (which have more efficient electric usage) were going for between 170-200 with ~68% of the hashpower. Now that the s5 has been released they seem to be going for around $140 or so, less in bulk

I seem to think the OP is somewhat trolling, regardless if he plans on selling these or not because of his ridiculously high prices. This is more then even BFL's most recent preorder price
