Bumping this thread to give a shoutout to the 1972 Defil I owned a few years ago. I traded the bass away quickly after doing some recording, but I love and still use its sound as samples from the recordings I've made. Even ended up on a Ghanian hip-hop track that got airplay on TV in Accra for a few weeks. These early Defil Rytms with the Bisonic-looking pickups and fully hollow bodies have a really nice sound. I remember I put groundwound strings on it, maybe GHS. The later Rytms with the pickups Defil would use later... don't know if those sound as cool.
Also something that might surprise many - it's still quite possible to get an early Mayones bass for under $200. They're mostly nothing fancy, though I did spot an Explorer-shaped one a few months ago, but historic. You can also find early 90s Mensfeld basses in that price range.
Here are a couple of early Mayones logos...

...or at least what's left of them.

As far as newer builders go, Leswar is doing some "alternate history 50s" styled basses, and Lootnick has made some really wild designs.
