've got a room without a cable outlet and want to be able to run my digital cable box which has my dvr and stuff in there. anyone have any opinions on which transmitters are good? i saw this at best buy but not sure how reliable it is:

Now they make it.

I was trying to engineer something at the USAF dorms since the only TV that had cable was the main rec rooms and we were allowed to have TV's but no cable feed.

Could you believe that?

i think its closer to 200$, but worth it.
