Pip -- English concertinas are often cheaper than Anglos (30 key Anglos, anyway). This is because you aren't competing with hoardes of Americans whose great-grandmas once lived next door to someone who nearly drank a pint of Guinness buying up the world's reserve of decent Anglos to play Irish music on at 200 mph.
