Keep seeing post about people wanting S9s. If you pay 30% more for your miner than you need to run it 30% longer to pay for it right? If you have to take another month or more to pay for it why bother? They will be for sale again before that. And don't think for a minute that 3rd party dealers are selling you miners they have already. They have some that are going to come in the future then they will ship them to you. You will be waiting anyway.
No one is going to sell these things without massive mark up.
