MacBook Restore Disks Model Specific?

I've lost the restore disks that came with my MacBook and am trying to find a new set on eBay. It looks like the disks say what model they are for (e.g. 13 Inch MacBook, 15 Inch MacBook Pro). Some of the disks for other models of MacBook are going for much lower prices than the one specifically for my Macbook. If I buy one of these restore disks for a different laptop than mine will it still work?
