My favorite D whistles are from Killarney whistles. They're very consistent and easy to play. They take a bit more push than some and are louder than the old whistles, not quite as fast, but they have the sweeter sound of the traditional tin whistle and they are nimble and predictable in the way they respond to ornaments. I get a passable C natural with cross fingering.
Yes I think the Killarney is probably the best value in whistles nowadays and ideal for beginners who don't want to go through the potentially lengthy process of finding a great-playing Generation Feadog etc (or finding a decent-playing one and modifying it).
My Killarney D plays uncannily like my favourite D, a c1980 Feaddog Mk1.
About "a bit more push" my Killarney has the easiest 2nd octave of any whistle I've ever owned, slightly easier than my old Feadog, which previously held that distinction. The Killarney also has a fuller low range than that Feadog.
About the crossfingered C natural, it was too sharp using the body my Killarney came with. I switched it for an old Generation D body which gives a great C natural. (A bit of tape would accomplish the same thing.)
