Here's my small assortment of whistles, from top to bottom in the order that I acquired them.
Grange Craft "Traditional Irish Tin Whistle" in D, apparently made by a family-run Irish crafts business in Ovens, County Cork. I bought it from a Celtic gift store in a US coastal town years ago when I didn't know anything about whistles. It tends to screech a little, and the tone isn't as nice as my other whistles, but I keep it for sentimental value. There's nothing like your first whistle, after all.
Oak Classic in D. I got it last year when I decided I needed a better whistle. It was the only brand available at the local music store not far from where I live. Clear and bright tone.
Clarke Original in D. I really enjoy the mellow tonal quality, breathyness, and lower volume.
Generation whistle in C. I decided to try different keys, but so far this is my only whistle not in D. I got it at a local music store which shall remain nameless, when I was visiting another state. They had a good selection of whistles, but didn't allow you to try them before buying. It turned out the intonation is ever so slightly off. Also, the shop's price and barcode stickers left lots of really sticky gunk, and I ended up scratching up the brass finish trying to remove it.
Chris Wall low D whistle. Probably my favorite out of all of them (so far, anyway).
I think I'll go for a Feadog next.
