Geez, if you have the money to go get one. GO GET ONE!!! Why if you hardware has any value at all, you should get one. Need I tell you about all the people that wish they had fire extingushers, when their houses are burning to the ground. How about people that wish they had changed the brakes on their cars when they are watching their wrecked car. Lets talk about this little boat called the R.M.S Titantic, need I say more.
How many times can I beat this stuff into peoples heads. Always expect something bad is going to happen. ALWAYS!!! Prepare!!!
