Welcome back forum friend....
Well...your question is not easy to answer.
It must be said that for certain models they no longer make replicas...and therefore it is not always a good idea to resell them. For more recent models, new manufacturers have appeared, with copies of the movements as well. The prices are therefore even more exaggerated.
For example, I have a Pam 286 made by Noob that I don't think is in production anymore.
So you have to see exactly which models yours are.
