Great advice Jautor, I just went through this math on my own.
I don't like the "leasing of the box" idea. For me, with a Genie and 2 mini boxes, the leasing fees alone were $27/mo ($15 +6+6)... there are 3 of us in my household with 4 TV's planned. If I plan on only 2 people watching different live shows at the same time (my wife and I watch together, or I'm on the computer or watching a blu-ray in a different room) then another consideration becomes putting in a Genie in my main viewing area with a second HD DVR run through an HDMI splitter. A 1x4 splitter is not too pricey but still spending $1k (for an HDBaseT with receivers) to save $6/mo doesn't make a lot of sense. HOWEVER, I have a blu-ray changer that I would like to distribute as well, making a 4x4 matrix more desirable.
My distances from a matrix would be 120' max (already pre-ran dual CAT6). I've been tempted to try the monoprice 4x4 matrix. They have a new 4x2 HDBaseT matrix as well. Ultimately, I decided to work on my house, and will probably wait for the HDBaseT matrix prices to continue to drop before pulling the trigger. There are so many other pieces of electronics I need to buy for now I may as well suck up the leasing fees and pay that $82/mo in the second year.
