You should be able to search online for numerous guides and info on reloading. Initial cash expenditure can be hefty, depending on what equipment you buy, but if you shoot a relatively expensive caliber (say, .40 S&W or .45 ACP), and you shoot a lot, it will soon pay for itself.
I've done it on somebody else's equipment. It can be a very 'Zen' experience, but you can't be distracted while doing it. Need to make sure you don't overcharge cases, or undercharge them, too.
Once you get the equipment set up, it's relatively straight forward.
Since I shoot 9mm, I'm not too worried about ammo costs, so I don't reload at this time.
