If you're loading straight wall pistol/revolver only, seriously consider the Dillon Square Deal B. I've been using one for more than 20 years, along side my Dillon XL 650, and it is one excellent machine. You can start out simple by loading one round at a time, similar to single stage, until you become more familiar with the process. Then move to progressive. After you get proficient with the machine 400 an hour is easily obtainable. Go to Dillon's website, and watch the video, or do a YouTube search for Dillon Square Deal B.
You still need several accessories such as, scales, calipers, bullet puller, hand-tools, etc.
I can't speak for the customer service from the other manufactures, but I can for Dillon. They are excellent.
Remember you get what you pay for.

Oh yeah, you buy the Dillon, then decide re-loading isn't for you, you can sell it easily without taking a bath. Just look around, and on eBay, for what used Square Deal B's are going for.
