Well, Apple no longer makes the Airport routers so you'd have to go for a used one. But recommending a router depends on a lot of factors. How large is your home? How many floors? What materials is it built with? Does your ISP provide a modem with built in wifi? Where would the router be situated in relation to the rest of the house? How many devices do you have? Will you be transferring a lot of files within your home or streaming HD video to multiple devices simultaneously?
I used my Airport (an older G model) for years but eventually retired it because the far corner of our house, my bedroom, had almost no signal, so I opted for the Eero mesh system. That works well for my setup (Gigabit fiber, two teenage kids with their own laptops and phones and different tastes in movies and TV shows). Yours will be different.
Try with a Wireless-AC router within your budget to see how it works with your situation. You can't go far wrong with the major brand names. What you'll find when doing your research is that there are always a lot of 1-star ratings for any particular router. Unless the 1-star ratings heavily outweigh the higher ratings, that just means it didn't work for those people for some complex reason related to the location. If it doesn't work for you, return it and try a different one.
