I've been loading for about 50 years and still use the same single stage press I got when I was 12 years old. I load for 8-10 rifle cartridges and 6-7 different revolver/pistol cartridges. I weigh every rifle charge on my RCBS scale but don't weigh my handgun charges. With the handgun rounds I have no trouble loading 100-150 per hour once the cases are prepared (sized, primed, mouths flared).
Go with the single stage if you don't shoot competitively and don't need a couple hundred rounds a week.
