I have used RCBS Uniflow, RCBS Duomatic, Redding, Belding and Mull, Lyman 55, Lee, RCBS Little Dandy, and Culver. I like the Culver the best, but it is the most expensive by a large margin. Second to that, I would prefer the RCBS Uniflow, with large and small drums.
PS: I am not a fan of electronic scales or dispensers. I trust gravity.
