Haven't used it for a while, but iirc, it requires a minimum amount for first transaction in irder to open a channel.

Yes this is true, min 10k sats incoming first tx (so about $3-4). It's instantly accessible at that point.
I typically describe it to the person as the cost to establish a connection, at which point they enjoy the low fees for sending/receiving.
In my experience they take that at face value and it doesn't phase them at all. Plus the speed of the incoming tx gets them quite excited.
