Can anyone suggest how to get a good DVD copy of the TIGER Install Disk for my son who is away at school?

I bought a FAMILY PACK so I've paid for the use of it and am NOT selling it or doing anything illegal. Just keeping it in the family but, want a Boot disk with each machine.

Specific details would be helpful, please. I can follow instructions, but need them to be step-by-step since I am still learning many things after many years of being a Mac user. This I'm new to.

Thank you.
