Unfortunately at some point ‘old tools’ became a thing on ebay and the prices went up. I bought a set of 8 old style Marples chisels for a tenner years ago, you won’t find them at that price any more. I’ve examined the Irwin set you linked to in the shop and they are excellent. A cabinet maker would want to put some hours in polishing the backs to take off the machining marks but their out of the box sharp alternative costs £80 (for a single one inch chisel from Lie Nielsen, for example).
