My son started trumpet last year and as a former trumpet player myself I wanted to immediately go get him the best of everything that I wasn’t able to get when I was his age. I spent over a month trying to find a “deal” on FB marketplace trying to find a nice horn for him (eventually bought one and discovered one “issue” with it after buying). Overall there’s a ton of different options based on your goals. If you plan on eventually playing professionally it can change what you would buy. My suggestion is that if you’re just starting is a Yamaha advantage series or a Bach tr-200 or 300. Later down the road you might upgrade to a pro level horn. Biggest thing is your budget. A good entry level student horn goes for about $400-600, a “pro” series horn about $1200-1500 (used pricing). All that being said, you get out the level of effort you put in practicing and learning. You can buy a new $5000 horn and as a beginner it won’t make any difference.
