A 4 tuner ceton card costs $200 right now on Amazon. Which equipment are you looking at?
your correct but still $400 in upfront costs imagine what manufacturers would charge to build an MCE pc
and you still need a high end pc for this not to mention 4 cable lines and 4 cable cards. and again if the cable co moves to ip based those cards are useless this is the reason i have not done this
