Bench Source is the best in my opinion, IF you are doing multiple sized cases, adjusting the torches and timer just takes seconds and you can switch annealing brass from 223 to 400 Warlord length, no additional special parts ever needed, no programming or setup, just turn it on adjust the height of torches and set timer and good to go, easy to set up a cold water tray to catch brass if you want but I let mine cool outside so I don't have to dry them
