It is expensive but that Frient keypad is what I have and it’s fantastic. Been running it for about a year now and it’s rock solid. I’ve even repurposed Nest tags to work with it.

I’ve seen tons of people buying these Xfinity Xhk1-ue keypads to repurpose for dirt cheap. I’m seeing some for less than $20. Lots of guides online.

You can also find more modern versions of things on AliXpress if you know specific brands to look for.
