Hi Todd,
Thanks for the post, sorry for the delay in my reply to you. I did a little digging and found out from our purchasing team that the production of this pump is going to be very limited at the moment, until December we expect to get only a few. To prevent a major back log of back orders we have decided not to place the 6105 on pre- order status.
I apologize for the inconvenience
