Sorry to hear ): Bin cages are super cheap and as long as you don't mesh the sides of the bin, it's chew-proof. You could try keeping Spice in a bin cage for a while until he breaks his habit if you don't want your cage to go to waste.
My hammy chews on anything and everything so I don't want to risk buying a huge expensive metal cage for her just in case she does turn out to be a bar-chewer. I only mesh the top of my bin, and the only noise i ever hear from her is the whirring from her wheel at night.
I hope you find a solution soon, good luck
