I found this TEB480 alto trombone and discovered it is almost identical to another brand with the price point twice as much.
This Horne has a very good finish, really nice slide, and very solid construction. Add a 10th the price of a professional Horne this is a great start for learning this instrument.
The sound feels a little bright and stuffy, but that could be me though the horn, being built very solidly, might use thicker metal than on a higher grade horn.
Regardless, for the price and the construction quality and the care and speed of delivery. This can’t be beat
