Has anyone here raised queens artificially? What is your favorite system or technique?

I've thought about doing it, even looked at a queen kit. I don't really have the time this year, so far behind on planting and getting the yard straightened out.
I've taken some cells from frames and rubberbanded them to another frame in a NUC and they have hatched but thats only been once or twice.

Have you raised them in the past?

No at this point I'm researching. I put a frame of brood and eggs in my friends queen less hive Sunday.
