There is absolutely no way in hell that the components inside a router can possibly add up to $500. Beyond a certain point things that are more expensive are just more expensive because they are, not because they represent better quality.
Routers are commodity items, there is absolutely no way that a router costing $500 is demonstrably better than a router costing $100
$500 is not an unreasonable price for a router if it’s actually good and comes with a good warranty.
