Unless you have serious ADD issues, reload. Financially it won't make you rich, but you will save money on a cost per round basis (unless you are really lazy about how you buy components....)
NOTE: due to the "explosive nature" of powder and primers, many web/mail order places stick you with a HAZMAT surcharge, hey they have to pay it so you get it passed on to you). I suggest you keep this in mind when you're looking to buy them. I suggest you find a decent place nearby, if you can, and even if the listed price is a couple of bucks more per pound it will work out cheaper than mail order.
I've had better luck finding deals on bullets on the web though. Many places will periodically run "free shipping" for bulk purchases. I am not picky about my range/practice ammo, so I'll just keep an eye open for the deals and work up loads for "deals" that I haven't yet shot. MidwayUSA has hooked me up with free shipping on Winchester FMJ and generic "copper plated" bullets. All of them have done well for me.
I bought my .45ACP and 9 mm para dies over Christmas and have more than paid for all of my basic reloading equipment (Hey, I bought the Lee stuff, so there wasn't THAT much to pay back, plus the rapid increase in retail ammo prices turned a 1 year payback into a 6 month payback!)
Now that I am reloading .223/5.56, I look to save even more over the mil-surp and WWB stuff I've been shooting.
