I wouldn’t spend money on the TX12 at this point. That’s their most obsolete radio. I expect it will be retired soon.
Have you looked at the new TX15 at all? Otherwise, hold out for the used TX16s. People are always upgrading. In fact a lot of people have upgraded from the TX16s to the GX12 because they like the form factor better, so there are more TX16s on the used market now. Swap meet?
Hmmm....I wanted something with ELRS because it doesn't seem to be going anywhere anytime soon...Also I just kinda like the modern features in more modern radios
