From Kaboodle.com, here are 6 things they say are best bought new... don't be a cheapo when it comes to:
Cribs (dropside cribs have been recalled and are no longer recommended)
Televisions
Mattresses (Do you really know what happened on that mattress? You'll probably get years of sleep sweat and other remnants you’d probably like to rest without.)
Digital Cameras (Have you ever owned one you didn't drop? They dropped it)
Hats (Have fun with their sweat, and skin conditions )
Makeup (Great way to get an eye infection, colds or even cold sores)
