For something that’s easy maintenance and is under a hundred bucks, I’d recommend a good plastic instrument. Zen-On (Bressan model), Yamaha (Ecodear model), and Aulos come to mind. I have a Zen-On Bressan alto which I like very much as a good backup for my wood instruments. Sarah Jeffrey has an instructive video on Youtube in which she compares various plastic instrument. You may find that helpful. Let us know if you need suggestions as to specialty shops where you can make a purchase once you decide.
