A good VR headset should give you sharp visuals, solid tracking, and a game library that keeps you busy for three or four years. You want hardware that handles modern releases comfortably so you are not forced to upgrade again twelve months later.
Hardware makers reliably reveal new headsets in late autumn ahead of the holidays. When those hit shelves, the previous flagship models usually drop right to around $500, giving you high-end performance for a much lower entry cost.
Keep in mind that a 0% intro APR is a firm deadline, not free money. If you still owe money after the 15-month window ends, standard variable interest applies to whatever balance remains on the card.
