You will get bombarded with mails selling you trials and lines, however that's all great the real test comes when they stop working, no one can offer a great service, was so much better when no subs were required.
I am now looking for a dual tuner box, KV I think is now a old box, even on a dual tuner box I will need subs just not sure who is a good provider out there, they are all just out too make quick money.
