Will wonders ever cease...

Golly gee wilikers!  I must not be the only one who has problems with nearly destroying the bottom of her oven!  There are an array of folk out there selling the very solution to my problem: oven liners!  You place one of these non-stick rectangles into the bottom of your oven and just wipe up all your spills.  Truly, will wonders ever cease?!?

Do you think there is an easy solution out there for people who tend to cook more charcoal meals in their ovens than edible ones????
