I currently have a VIP722 DVR with an external hard drive. I'm looking at buying my own VIP722K to put in the bedroom. I asked DISH about this and they said no activation fee for VIP722K but $14/mo more having it. That figure sounds really high to me - is that what others are paying for a 2nd DVR in their home? Second question, can the external hard drive from my VIP722 be shared with the VIP722K if I activate the VIP722K on my same account in my same home?
