I've always played on Feadóg, and I can not be disappointed with this brand. How could I anyway? A 5 euros flute, price / quality ratio is excellent.

I play mostly with a version in D (D) non-tunable

Note that Andrea Corr (The Corrs group) has also its array of whistle (in addition to its two walton, his 2 generation, and its chieftain).

In short, it's all good
