My choice of instrument would change slightly with the repertoire under consideration. I have two baroque trumpets, one by Egger and the other by Tomes, and each has its advantages. The Tomes is better at A=430, and the Egger has such a great sound in baroque chamber settings, for instance. I wouldn't waste money on a baroque trumpet that doesn't play well; it's enough work with a good instrument, and you get what you pay for.
With the weak U.S. dollar, European made instruments have risen in price lately. But the American-made Naumann trumpets of the past few years are worthy of recommendation, and their prices aren't fluctating with the value of the dollar. (A Naumann Eklund model would be good; many of the earlier ones have intonation challenges.)
If you want to go no-holes (true natural trumpet) Egger historical models are clearly the best.
To learn more about the various choices I'd recommend you get in touch with Barry at
The Baroque Trumpet Shop. If you are interested in a used Egger trumpet, PM me and I can put you in touch with a friend who is selling one.
Hope this helps.
