I’m on my last batch of fixer-uppers.

If I get another oldie, it’s one that someone else did the labor.

Parts are pricey and in more cases, take longer to get in my case.

When you buy an older vehicle, you MUST do some research FIRST !
You have to buy a popular brand, and one you KNOW that's easy to get plenty of after market parts for.
Ford and Chevrolet are a good start for your research, but be sure that they sold a lot of that particular model.
Do a parts search FIRST for the type vehicle you're considering, and after you KNOW that you can get parts, THEN start looking for a "Frame Off Restoration" of that vehicle.
It IS worth your time.
