Anyone know how much longer the Dish DPP44 switches will be available? Mine is working fine, but wondering if I should buy a spare while they are still around. Appears to me that Dish is getting away from using these switches. I run single cables and then use separators for my four HD DVRs throughout the house. Don't know of any other solution should my present DPP44 go south. And yes, I have the $5.99 a month Dish extended warranty. Thoughts?
