Honestly, I was never looking for one, but friend of mine suggested me some local guy. He moved to another providers but Im using the same one for years. Friend told me my guy is bad, but its not for channels I need (I guess lol). Anyway he is finding new providers on forums by direct messages, but also on some random google search or reddit/lemmy recommendations for example. Anything is safe to try afaik, you usually get free trial for 3-7 days. Its best to test when its time for some super popular foodball match or something like that
