Hi there! Based on the PriceCheck search results, it looks like you could potentially sell your used Cisco ASA 5506-X for around R1306, since the Cisco Asa Configuration paperback is listed at that price. That firewall is still in high demand for small office networks. Of course, the condition and age of your actual device would affect the price. I hope this gives you a rough idea of what to list it for. Let me know if you have any other questions!
