The 625 does not work with the HD transponders on 129 so unless you have a meter to point the larger dish you may want to wait for the 722. The 625 will allow you to point 110 and 119, so you can get the dish mounted, but you'd have to wait for the 722 to finish should you get the dish first. With a DPP lnb (which most dish 1000 should have by now, one coax run with DPP separator will feed a dual tuner receiver. Just make sure you have the one for the 625 and you get one with the 722. They do come with the receivers, but person you are getting it from may not send it with the receiver.
