Star Choice gets charged by some of the channels based on how many recievers are in the house - so its not ALL just a cash grab.
$4.99/month x 12 = $60/year.
There was a remote extended in The Source by CC catalogue today for $70.
100' of Coax cable to run between your TVs runs about $40.
Splitters are around $10 at The Source.
Add in the time and effort to drill holes through your walls, floors, and ceilings (plus vacuuming all that pesky drywall dust) to string coax, and $4.99/month isn't looking too bad. Considering you're getting 2x the programming and a lifetime manufacturers warranty on your receivers, and it seems like a pretty good deal, at least to me.
As always though, your mileage may vary...
