I would avoid that type of horn shown for the now-sold Reynolds. It is a smaller horn, and one that was not popular. Therefore the response and intonation may not be as good as the horns that were more the bread & butter for the instrument companies - the 3-valve euphonium (often called a baritone horn). The King I linked above would be a solid choice. However, if you want a horn that is easy to play and lighter in weight, I'd go with a Conn 3-valve. Here are 2 current for-sale items, which are similar to the horn I played before I got my 4-valve King in high school. Easy response, sweet tone, good intonation.
