How much does a Wi-Fi router cost?

Could you please enlighten me on the typical price range of a Wi-Fi router? I'm in the market for a new one, but I'm not quite sure how much I should be budgeting for this purchase. Are there any factors that influence the cost, like brand, features, or performance? Is it possible to find a reliable yet affordable option, or do high-end routers typically offer better value for money? I'd really appreciate your insight on this matter.
