Stop in for a cup of coffee

So, who are the cut the cable gurus here? I actually cut my cable before I went to Vietnam in January. Still have Wi-Fi. I'm not an audio visual or TV expert, not used to dealing with all of that. I've just been watching stuff on my laptop YouTube also and whatever else I can get on there. I'm wondering what kind of streaming device I should use, if any? I have one LG TV that is a smart TV and it gets some channels. The other two TVs are older and not smart but good enough flat screens for my use. But what I'm looking for is to be able to get MASN So I can watch local baseball here. I'm trying to figure the least expensive way to do it, since I'm usually not here at my house in America for 4 to 6 months out of the year.
