I think it's important to realise that there will always be free relays. You'll never get locked into a paid only nostr environment.
My relay is there to give a little something back to the community. There's a small 8888 sat charge but you won't see any spam on it, simply because spammers won't pay if there is a free relay they can spam instead.
Additionally, the paid relays I've used aren't swamped with users so as a result, they are quick.

If you want to try the relay, send me your invoice and I'll repay it.
