I think I enjoy reloading more than shooting. And it can be economical, too, particularly if you're shooting certain big-bore cartridges. Not too long ago guys were telling me that they wouldn't even consider reloading 9mm because it was so inexpensive, so I happily picked up their brass and tossed it in my tumbler. The brass is the expensive part (at least before people started to think that primers are worth $100 a 1000) and if you can pick it up once-fired from a friend or acquaintance that saves big. Most of the brass you find laying on a range is once-fired, as reloaders take their brass home with them. And there are on-line sources that specialize in once-fired brass. I guess the one expense that's hardest to quantify is your time. I find it enjoyable and relaxing to spend a couple hours at the bench, but if you'd rather be doing something else or find it a chore, then maybe it's not for you.
You don't need to spend a fortune on equipment, either. I still use an ancient CH single-stage press for a lot of my reloading. That was the first press I ever bought and even though I now have a setup that will load MUCH more quickly, I still enjoy the single-step process for low-volume loading. I just used it to load 40 rounds of 6mm CM a couple days ago. I think Lee still sells an expensive "starter" setup that has everything you need to get going.
Right now would be a tough time to get started as it's tough to find primers, and projectiles are getting harder to find, too. But it's my opinion that it's absolutely positively worth doing.
