I know of relay.exchange only but im sure there must be other lists out there
Discussion
You can just go to any of these. 
Third from bottom is best 🤙
Also 🤫 there’s a quiet sale on this one for Satoshi’s birthday this month.
Minor update,
wss://nostr.plebchain.org has merged with #[5] and we are now offering a range of #Nostr services.
The new relay url is wss://ca.orangepill.dev
We made the old url compatible with the new one, but I would suggest updating it 🤝
We also wrote this beginners guide with step-by-step instructions to getting everything from paid relays, NIP-05, LN proxy/forwarding, etc. setup on #[5] using #[6] services with a single form to fill for new users. It will send you a login/management password via dm as well 🤙🏼
