I currently have 2 612's and 1 722 (which is used on one tv). However I own 2 regular receivers Id like to hookup however Dish wants to charge $99 to come out and all the wiring is done I just need a splitter so I was wondering which ones and where to get one online. Dish said if I bought it myself they could even help over the phone hooking it all up but if its anything like directv its pretty cut and dry and shouldnt be a problem. So I currently have 3 lines hooked up and need 5.
