VUTV is currently a reseller of NexTV. Thus, they offer the s a m e programming. In terms of cost, call up and find out who offers a better deal. I would tend to think dealing directly with NexTV, rather than with a middle man, would be slightly more cost effective. On the other hand, for someone with less tech savvy, perhaps a reseller will offer better customer service.
Finally, don't be afraid to negotiate. It seems certain things are negotiable, like "activation fees" and getting anywhere from 1 to 3 months of subscription free.
Cheers.
