I disagree. Depending on what you buy it can be done for pretty cheap. Obviously it will take some time to recoup your costs if you're only loading for one gun, but at $4 a pop for factory ammo it is certainly still economical long term.
OP it will all depend on how much you shoot. If you're going through 1 or 2 boxes of ammo a year, its gonna take a while, but if you're shooting 5 or 10 boxes a year it could pay for itself quite quickly. All you really need is a press, a scale, some components (hope you've been saving your brass!), and a few small tools for trimming and chamfering. If you buy used and look for deals you can likely get a press, scale, and the small tools for something in the ballpark of $100-200. It was under $100 for me when I did it, but that was like 7 years ago.
$1000 is ridiculous. I could buy brand new stuff for half that or less.
