Yuri (of this parish) makes wooden tabor pipes down to Low D, which'll of course look more 'authentic' than plastic Susatos or metal Generations. Bear in mind that you'll be playing in the upper octave, so it'd be less screechy than the High D tabor pipe but still in the lower octave of the High D (as it were). Or there are several other sizes on Yuri's site which become progressively cheaper as the pitch increases.

It's better outside, perhaps - if you've heard eg a Morris musician playing a High D outside, you can see how they can do a job and be clearly audible. I can imagine that a higher pitch could carry in a crowded auditorium too

There's a list of makers here:

That website's worth a look anyway.
