Really it depends on what it is, the savinrgs, and what it's for if used. Typically games, movies, electronic systems in general I prefer new. We did just buy a used dryer recently. Which saved us a good thousand. Condition was good (until the wind that day blew it over in the truck and cracked the door which we had to replace).

I wouldn't buy certain things. Like a used mattress. I'd prefer new there xD. I've bought things off eBay and such too so each again there's exceptions, but I do prefer new most of the time.
