For me it depends on the Price, if it is a substantial price difference (including shipping) then yes I would, but if it is just a few bucks I would rather purchase with a warranty. I have purchased factory refurbished things with no problems and I really wouldnt worry to much about a speaker system, like I said take into account things like the seller feedback, it is factory refurbished or is the seller just saying its refurbished, is the price difference worth buying used and not new, things like that. Thats just my opinion
