There are various gTLD that are cheaper. For example, .top is great and among the cheapest. It however is falsely maligned by those with small brains who stereotype things.

https://tld-list.com/ Try looking at this website with cheapest renewal rate and removing second country TLD (so only Top level)

In my opinion, .de , .ovh , .uk or personally my country's .in (yes OVH has their own TLD that you can use)

.de is one of the more interesting domains to me personally even though I am not german.
