I think the first question you need to ask yourself is how many rounds do I shoot a week, this will play a big roll in what type of machine you need, single stage, turret or progressive. If you plan on shooting 100 rds. or less a week you can get by with a single stage press, with a turret you can turn out 200-300 a week. More than that then you want a progressive. I use a Lee turret, have done 10,000rds in the last year. Output of 125-150 rds an hour. Very easy to change between calibers. Die sets are very good quality and inexpensive. I would write some more but I injured my arm and typing is no fun. There are a lot of good machines out there. One thing you need to do is read, read and read.
