I have been looking at the cupularva queen rearing system that Betterbee sells. You don't have to graft larva.
On the surface it looks good for my size of bee keeping (small). You get the Queen to lay in cups, then put one cell per nuc to finish and mate. For me this would be a step up from just doing a split and letting them raise thier own queen. I don't want to buy queens as I have two hives with a feral strain that I want to keep going. They do better than the Italians by a mile so I want to make increase, but I want to roll my own.
Have any of you used this system or one like it?
