I've dropped my HD because I never watch it anymore, but I would also like to get rid of my leased 622 so I don't have to pay the $7 HD fee. I've gotten different answers (about the cost to get a 625) from cust service the two times I've called to ask about getting a 625. It looks like I would need to pay about $99 to lease the 625. Should I just buy a 625(used or new?)? Will it be an easy swap? Thanks for any advice.
