alby hub is great, i've been running it for like 8 months now, on the cloud hosting plan, cost 21ksat/month, and i use it with alby Go which lets me do payments on my mobile.

you don't have to learn very much to get started with it. mainly just do read their docs well and open a few channels, i recommend at least one in and one outbound, but if you are mainly gonna be receiving payments, get two inbound ones (cost about 10-14ksat to open). definitely make sure you keep a few more running than you think you need because sometimes they get closed. the current version also includes rebalancing so you can make sure you spread your sats across your channels and don't get stuck for a week with the one channel you had a lot in, stuck waiting for it to go back into your onchain wallet.

you most likely will not run into any expensive problems with it, just occasionally maybe you have funds stuck in purgatory for a while until they come back to you.
