Cheapest 4-disc G1 SteelBook available

[Nisei]

Guys, I've got a precious 4-disc G1 SteelBook with a damaged inside. I want to repair it by buying another one and transfer the inside to the damaged one.
Of course the cheaper the better. So, what would be the cheapest 4-disc G1 title available at the moment?

Spawn is the only one I can think of. I bought it a while ago for 5.99

Sounds great. But where did you get it for that price?

Not anymore. Even used copies are over $25
