Personally I don't get the argument against enums. From what I can tell it's purely to do with the symantics of what Typescript is, rather than any inherently bad property of enums.
Honestly, I'd say around $2-5. It's not that I wouldn't value better quality search but in a world where search feels like an almost 'invisible' part of browsing the web I'd struggle to pay that much. I guess it's comparable to what I feel is a price I'd be willing to pay for a VPN say compared to a coffee subscription.
This also isn't a reflection of what I percieve the work in building a search engine to be but more my subconcious perception of what I'm getting.
