Question Author
"like you can buy a kiddies set of watercolours for peanuts, or pay 10 times the price for artist quality Winsor & Newton's."
Still anecdotal, I'm afraid.
And that argument is SO poor - do you buy Apple iPad leads (about £20) or unbranded ones (£8)?
Most leads (and I suspect but as yet have no proof!) like most inks are produced in the same factories in Taiwan or Shanghai, and again (I suspect only) differ mainly in whether they're shipped out in Canon wrappers or 'Bloggs' ones. (This used to be the case (proved) with Soap Powders in the 60s and 70s, when the same powder was used to fill different boxes, which, of course, were sold for different prices. Dearer, for the more discerning "I only buy what's best" brigade, and cheaper, for the "I only buy what I can afford" shoppers.
Science, please, not stories.
