You'd need to provide a bit more details like language and what country you're going to be based in (at the least). I have seen cases where payments have been rejected (service cut off) and where credit cards were shut down (considered fraud). I'm based on Canada and have helped some of my neighbours source services for chinese language stuff (mostly by the regular cable providers who use IPTV stuff) or through a few web sites. I have tried a few android boxes, unfortunately these tend to have a habit of the apps getting shut down shortly after they're bought and at a considerable cost (these boxes often cost $100+).

What you might consider doing... Head to your nearest ethnic mall ( in my case, Pacific Mall or First Markham Place for chinese language stuff) and snoop around the A/V shops. They will often have providers listed there. Then do some research on the company (eg, age, channels provided, where they're based, etc.). I'm not saying this to be annoying. It's just that I've been burned (and seen others burned) by some of these. With illegal providers, often your credit card will get compromised. Some of these pirate their signals and get shut down... or in a few cases, since the provider is not within country, some of them get flagged and blocked by credit card providers as suspicious transactions. Depending on what you're looking for (eg, a source of news for people) there might be free legit sources as well.
