No worries, if you're looking to depend on one or two relays then I suggest nostr.wine which cost around 18k sats lifetime payment and then is a very high speed performant relay. Then I suggest using one of your own that you run at home. Redundancy is good so don't just use one relay because if that relay goes down then you could lose your Nostr events. Any questions let me know and I can easily explain the technical ins-and-outs :)
