Take a look at Keychron. They have a lot to offer for around your budget and they go on sale frequently.
Are you looking to be able to swap switches out? If so you will need to find hot swappable switches.
If you care about backlighting they might be a little more expensive. But Keychron is reasonable. I’ve had their K2 for years and it has a better feel in it vs Corsair or Razer stuff in my opinion.
