Well your speculation is my story!!
Sea of Thieves sparked my interest in the concertina. Picked up a cheap Amazon one. As expected, that lasted about a day. I went to Liberty Bellows in Philadelphia and purchased an affordable to me used instrument. I replaced the straps as the original ones were not adjustable and were entirely too small for my hands. I ordered " Easy Anglo 1-2-3: A Beginner's Guide to the Anglo Concertina" and until it arrives have been using Concertina Academy's YouTube lessons.
