Bach Marching Baritone...Good Brand?

If you want a good quality instrument that has a good quality sound, get a 4 valve euphonium. The Bach B1160 would not be a good choice unless he is going to use it specifically for marching. Also, 3 valve instruments do not play in tune as well as 4 valve, and are often made of less quality, especially instruments made for marching. You should consider the difference between baritones and euphoniums also, baritones are cylindrical and usually have 3 valves, which has a sound more like a trombone, but usually not as focused or in tune, while euphoniums usually have 4 valves and are conical, which has a much richer sound of a tenor tuba, which is preferred by any musicians outside of marching band. A compensating system is preferred for a 4 valve euphonium, but can be more expensive. Bach is a very good brand for euphoniums, but you can also look into Conn, Yamaha, or Besson. My main suggestion is that you take him to the store and have him play different models since with brass instruments, they aren't like string or keyboard instruments where players can switch or play on a new instrument with no problem, with brass, the instrument has to match the physical characteristics of the player to get the best sound quality.

Keep marching horns in marching bands/drum corps. If he plays in orchestras and brass bands, get him a proper euphonium.
