Its 3 years old.. its got all the attachments.. ive read reviews and they r mostly good… But im having second thoughts, do u think its a good decision.. to buy a 3 yr old used dyson for 200 dollars…. its definetly an old model wat do dyson users here say… will it last is it worth 200… i need serious answers… THANX!!!!!!!!!
