Reloading is a very satisfying and rewarding hobby. It is also rumored to be economical after you buy all the equipment you need. I am still trying to verify that last part though, because after a few decades of reloading I am still finding stuff I need to buy. My wife cries when the Midway or Natchez catalog shows up in the mail :-laf :-laf :-laf
Equipment brand doesn't matter nearly as much as how much care you apply to the reloading task itself. All of the modern equipment is very well built, and you can turn out some VERY good rounds if you do your part correctly.
A single stage press is usually the best starting point, although some jump right into the progressive presses and never have a minute of trouble. Exactly the same operations are performed with both types, the progressive just saves you time because several operations are performed in parallel using multiple dies, whereas the single stage press requires you to run the cases through multiple times in batches after switching in the appropriate die.
I have reloaded truckloads of ammo with both types, started with the single stage, moved to a progressive which I enjoyed immensely for years while I was involved in various competitions, then a few years back I returned to the single stage press.
As a previous poster mentioned, buy a GOOD caliper. A good electronic scale will pay for itself in time saved watching the little beam scale pointer bob up and down before it centers. A sturdy bench is a must. Depending on your age, you may find that a good magnifying glass is just extremely useful, or maybe downright critical. :-laf
Things to Avoid:
1) Case-Miser-Itis: An obsessive need to find every last case fired so that you can reload it. Can result in much wasted time, cursing, and sweating as you crawl around determined to find that last Winchester . 45 ACP case that somehow bounced off the range partition and ended up standing upright on a crossbeam under the shooting bench. Severe cases can lead to paranoia as you spend more and more time watching nearby shooters to make sure they don't steal that precious stray 10-cent casing you have reloaded 12 times. This disease can sometimes be spontaneously cured by herniated spinal disks, heat stroke, or snakebite.
2) Die Hoarder Syndrome: Crows and some other birds sometimes exhibit an obsessive urge to gather and hoard shiny objects. Reloaders are sometimes afflicted with a similar disease and end up with 10,000 sets of dies crammed into every available drawer and cabinet in the house. They are unable to resist a "good deal" on a set of dies and will buy any brand, any caliber, even for firearms they do not own and are unlikely to EVER own. Extreme cases are typified by possession of many die sets in the same caliber, and some are known to go so far as to have multiple sets of the exact same brand / caliber of dies - one for using, and one or more spares "just in case". Warning: There is no known cure for this disease.
3) My-Brand's-Better'n-Yore-Brand Fever: An obsessive and inexplicable urge to obtain validation of equipment choice by trying to force everyone to agree that your gear is the best. Often leads to broken friendships, hurt feelings, and expensive sugar teat distribution. Highly infectious and spreads rapidly online. Cures have been achieved in rare cases by quarantining (banning) the disease vectors online, or by forcing the most vocal participants to spray-paint their blue, red, orange, or green equipment "Barbie Pink".
