It's easy to set up your own node. I recommend #Start9. I have used #Umbrel before, more user friendly but not fully open source.

You can buy an old mini PC for around £50 (€60) add a 2tb ssd and you're away.

If you can't get that going, look into #Zeus. You can turn your phone into the node. #Zeuspay will give you a Lnurl to set up for zaps.

There is no need for WoS custodial wallet. You could also look into #Alby.

Good luck
