If it’s a size that Hope use then their bearings are often the best value, quality option. (just got some 6902s from Wiggle for £4.20)
I’d stick to brands- SKF, FAG, INA, Koyo. I like Koyo because they come in a little cardboard box, like matchbox cars used to, this is as good a reason as any. Real cheapos are a false economy IME, I remember buying a pack of 5 Challenges and 2 were rough out of hte box, one shattered in fitting, one lasted entire miles before going rough… And the 5th lasted absolutely ages 😆
(not to say cheap bearings can’t be good but it’s hard to know when they’re good and when they’re shit. And sellers intentionally selling cheap crap are never good to deal with)
