I just added a 622 on the $199 promo (already had an owned 942). The 622 being installed this week. I am sending a leased 301 back to them, so I only get the $100 rebate.
They told me to get a second 622, to order after the first is installed and operational. I will return the 942 and get the $100 return fee, but not another $100 rebate as that is a one time deal (it is for adding a metal programing)
