Capacitive HMI stylus


I'm looking for a stylus for HMI with capacitive touch screen.
I found only Siemens 6AV2181-8AV20-0AX0 but it's too expensive (about 100 euro).
Do you know any companies/products? It can't be a no-name.
It would be even better, if it already has any kind of holder.

Thank you!
Greetings :D
