A sideways look from the Towers again
Lovely little industry running to cater for those peed off at the manufacturers prices. As you all know they use the Gillette razor principle from the turn of the 20th century: Minimal cost hardware to trap users within the system and then gouge 'em for refills.
However,
if you want your photos to have the same lifespan as, say, a small cheap car you will have to spend a very long time searching for decent refills and you will never know if the claims made are true.
I use the real ones where a major brand has its name to protect and I'm simply very, very selective in what I print. If you think more than one in ten of your shots are really worth printing you really should be doing it for a living - you'll clean up in the world of the pros
