Any Tuner/Metronome combo will also work.
Korg is a very good brand name that should last a long time (Mr. H has a Korg tuner from 1989 that still works just fine!)
Make sure you put your name on your tuner!
Any kind of portable music stand will work, even a full size one that you are willing to carry around.
Please stay away from the very lightweight metal music stands if you can help it.
Make sure you put your name on your stand!
