The amount of people who have quoted me in this thread proves that there is, at best, a very loose correlation between cost and quality. Is a £6k Fodera noticeably better than a £100 Gear4Music own-brand p bass? Absolutely! Do all the basses in between follow that logic in perfect cost order? Not at all.
I really belive that, if you'd never heard of any of the brands, you'd say my MIA and MI Fenders was near the bottom of my pile. Certainly below my Sire V7, which cost half as much.
