I only buy steelbooks that I like or can get really cheap in new condition. I would never pay over 20 pounds just for an empty case, that's how much I paid for the MGS HD steelbook, and that's only because they are my favourite games of all time! I have slowed down a lot now in collecting although I managed to pick up a sealed Soul Calibur IV one for 3 pounds yesterday and it's kind of got me back into collecting them again
