Hello, Altair.
See if you like the sound of the melodica Tom Teasley is playing under “Members’ melodica recordings.” It is a Suzuki M-37C, which costs about $100.
The Yamaha P-37D for about $110 is another to consider for more of a clarinet sound (in my opinion). Listen to Daren’s video on circular breathing.
