You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
I stand corrected, while my MBP did ship with Snow Leopard, I am able to use the Lion Recovery (after a firmware update). I wish Apple Support would have told me this before I spent $18 on new DVD's. Anyhow, thanks for your post, I can be up and running faster now.
