Hi I'm looking to buy a Fanuc based cnc lathe on a budget and I'm wondering what is the oldest era of machines I should look at before spares become super expensive or hard to get because of age.

Is there an era or type of machine I should avoid or aim for? I would prefer to spend around 10k-20k on the lathe (and Im in Australia so that may equate to a lot less in the USA) but I am flexible if spending more will get me a lot more, or similarly if spending less won't make a difference. It will be for a hobby/side business to start with. My friend has a Series 0 TD based lathe he can sell me, I'm not sure how expensive spares will be for it if something breaks.

Also if anyone knows if Okuma or Mazak are something I should be looking at (or another brand) please tell me. My main concern is spare parts and reparability above all else.

Thanks for any advice.
