Adding new switch to old stack

[SCOTT No2]

We have 2 SG350x-48 switches in a stack.  and we need to add another switch.  but I know that SG350x-48 is no longer sold.  what are my options?  these were replaced by the "Cisco Business 350 Series Managed Switches".  can one of these switches be added into the stack?  or do I need to replace the entire stack? Or buy a used SG350x-48 switch?  other options?

Thanks

Stacking Guide lines - until it states any where otherwise - hardware models and Firmware and IOS code should be same.

you are not worried about support - for temporary fix you can buy refurbished same model and join to stack.

when you have budget - replace with better model is wise for commercially and operationally.

Thank you.  I'll have to check for a used switch.
