Adding my two coppers here...
(edit 2) And I get to give mine without guilt, LOL, because I *am* the end of the US tour... take that glaubie!

I have had the pleasure of 'babysitting' the O'Brien Tour D whistle, nickel plated copper with a clear lucite fipple, this past couple of weeks.
I love it.
It is a totally different sound from my other pennywhistles. The sound is sweet, in tune and just a little breathy - I like that very much.
The tunability is a big plus, and it *stays* in tune as well (as long as you don't pull the stunt of taking it apart and managing to put the body back in upside down.. cough...)
I love the looks - it has definitely been turning heads with the distinctive clear fipple, and the copper showing through the holes and window to contrast and complement the nickel plating; the heft of it - solidly built; and the ease of play - two full clean clear and true octaves plus.
It does tend to clog a little, but that's easily taken care of by a good 'thwap' on the thigh, LOL (or any number of other theories that have been discussed on this fourm, and I won't pretend to know much about)
It has so impressed people here that a friend with a music store is planning to carry them and one of my whistling friends is ordering a set.
I was so loathe to let go of this one, that am in negotiations with Dave to keep it and get a set of the rest of the key bodies to go with it.
The individual whisltes sell for US$50. I would definitely suggest the set - The price is not bad at all, considering the set encompasses four keys - Bb, C, D, and Eb - with one head and the four interchangeable bodies. .. so at US$85, it is a good deal. I am looking forward to meeting the rest of my little whistle family.

I am very impressed with David's guarantee as well. I was wondering what I would do to protect the finish, as the nickel is wearing thin in a couple of high-contact spots on the whistle (this one has been around!), - He will replate when needed for the life of the whistle. In fact, with the 30 day money back guarantee, and the lifetime service, It's very reassuring. I would have been hesitant to spend the money myself if I had not been able to try the whistle, so, for me, this is a great point. (I have not been able to consider purchasing high end whistles, so I don't know if this is standard or not)

My thanks to David for allowing me to participate in the tour, and for being so gracious with me in our talks.
Of course, now I'm going to have to make *another* whistle case...
(edit 1)
Several people have talked about the head of these whistles (both pro and con), so I paid some closer attention to my own. I did not find the mouthpiece uncomfortable at all. One advantage of the Lucite Fipple is that it is not cold even when the metal of the whistle is.
I did note the sound changes depending upon the angle and position in my mouth, but I have noted that with other whistles I play as well... or rather, I've noted it in *my playing* of other whistles. I think that in *my* case, it is more the player and less the whistle that has the inconsistancy.
I do find it more breathy if I tilt it at a more tight angle. This may possibly be due to the shape of the head, and the 'no-blade' design, but I believe it is more the interference of my lip, and the sensitivity to the pressures of mouth shape adjustment. If I keep it well into my mouth, past my lips, it seems quite consistant to me.
