ya, i may have been a bit disgruntled when i wrote that, it was since you mentioned 'general audience' and my exp is hardly anyone pays for relays...  but there are some out there

wine is obvs the best, 
eden.nostr.land is pretty big
nostr21.com is one of mine only 21 sats
galaxy13.nostr1.com is only 13 sats

I've been tryin' to push for paid relays for a long time, but some days it feels like lightning has failed me because nobody even thinks it's worth it to essentially pay to solve a 'captcha' and would rather get spammed to deth.. lol 

 Thanks, I’ll check out the ones you mentioned, I’ve heard of wine and eden but never bothered.  

To me having to “top up” or pay every week/month is bad UX.  I love the Mullvad model - flat monthly pricing, but you can pay for as many months as you’d like in advance. 

 for rhese its a one time fee,.unless you get kicked 🍄
