I don't think it's worth it. You can download 10.7.1 from the App Store and very easily put it onto a USB flash drive (you can get an 8GB flash drive for less than $10 shipped from Amazon).
The total cost, including the flash drive, is around $40. You can also burn the DMG to a DVD if you want. And of course, you can always install it and/or redownload it from the App Store in the future.
