Domain registrar

Can anyone recommend a domain registrar who hasn't gone crazy with their pricing, supports DNSSEC and doesn't have strange tie-ins?
Gandi's prices have shot up over the last year or two. Cloudflare look great, but you have to use their DNS. Google's offering was really good, but now they've thrown in the towel.
Oh, and preferably UK based.

Thank you!

IDK about DNSSEC but otherwise Purely https://purely.website/domains/ fit your bill. Fiver a year of uk domains.
If they don't tell me what DNSSEC is and why it's important to you - and maybe me!

I use Mythic beasts for my DNS (and also a VPS) www.mythic-beasts.com
Not the cheapest (though less than my previous ones went up to) but they know what they are doing and support everything you want.
I've had no issues with them in the few years since I switched to them.
