Hi, I’m just starting on the whistle after a lifetime of playing the fiddle, so I’d love some recommendations of really good whistle players to listen to or look out for! I’m still playing my little Meg but deciding whether to go for a Dixon D or a low whistle next as well so looking for a variety of players to see what I really want! I’ve just been listening to Pat Tierney who seems pretty hot over the holes…
If it’s ITM whistlers you’re lookin’ for, there’s a sticky of recommended whistle albums to check out.
It can be found here:

Off the top of my head I’d say:
Paddy Moloney
Mary Bergin
Micho Russell
Joanie Madden
Hello Alest, welocme to the board.
Pat Tierney is very good indeed.
My opinion is that you’ll want to listen to a variety of players.
Joanie Madden, Mary Bergin, Micho Russel, Brian Finnegan, Enda Seery, are just a few from this list;

A nice sampler with transsciptions can be found here;

I’m partial to Kieran Collins and Enda Seery, but I have a pretty good collection of many others too.
Good luck and again, welcome.
Edited to add; Looks like Mr Ed beat me to the first post. Well done sir!
The credit goes to that extra cup of coffee this mornin’. 
I am a big fan of slacker.com… You can set up a free account and type in artist names from the list at the begining of the forum. (I have not done that yet) If they are supported artists they will be played with similar artists that you can ban or like. If they are not supported artists you can ask for them to be. I have been listening to their St.Patricks Day channel. It’s a mix of trad up to Flogging Molley’s. Which two of the band members made the station list. I think I’ll give that list a try.
Mary Bergin has already been mentioned. Her two solo CDs are Feadoga Stain and Feadoga Stain 2. Classics.
Less often mentioned, but older and at least at classic is “Tin Whistles” by Sean Potts and Paddy Moloney.
For the low whistle try the youtube channel of a fellow who calls himself tinwhistler. He’s not Irish - I think he’s a Catalan from eastern Spain - but there’s no CD I know of with such consistently good traditional playing on the low D.
EDIT: I also like Muireann Nic Amhlaoibh and Julie Fowlis, although both are primary singers.
They’re both in this youtube clip: http://www.youtube.com/watch?v=raOhfgsft8I
I second the recommendation of Muireann Nic Amhlaoibh and Julie Fowlis. Check out their album “Dual”. I find that their voices complement each other really well, and they have some really nice whistle work. It’s a very good CD with a lot of sonic variety, especially if you are one who gets tired of the same sound over and over.
You have to figure out the style you like. Mary Bergin is the purest of the trad whistling. Joanie Madden is a little more…contemporary? More dynamics in the whistle playing. Brian Finnegan uses some really interesting tonguing techniques and has some amazing compositions (The Ravishing Genius of Bones is one of my favorite albums). Michael McGoldrick plays on the lower end of the whistle spectrum, and likes to add weird stuff to the mix, like saxophone and trumpet, but he’s an amazing player on flute and whistle, and bagpipes as well. Morning Rory is his least experimental CD. Fused is more experimental, but very good as well.
Let’s not forget Kevin Crawford! 
Slainte,
