Depends on what it is. I have a lot of used clothes, furniture and games, and my car is used. My laptop was even bought second hand from eBay which was a bit of a risk for a $1000+ item, but I've had it for a couple years now and it's been amazing. If I wanted it new it would have been over $2000.

So as long as something is in good condition I don't mind if it's used. I wouldn't buy anything used in bad condition though.
