Never heard of Columbus.
Vester was a cheap Korean copy, okay for the price but nothing special. Don't know where you get the idea it was a lawsuit bass, but there is or was a Wiki entry on Vester that was almost sheer fantasy, including a claim that Fender was going to sue them for sounding like a Jazz Bass. Preposterous! There was never any lawsuit, they were just one of many companies over the years that got cease & desist letters from Fender for having headstock shapes or logos that were too close to Fender's trademarked shape and logo. Like the others, they backed down.
I wouldn't advise paying over £50 for one.
