As an older newby reloader, I went into it with the intent to further my interaction with the shooting hobby. I love to tinker and this gives me something to feel an accomplishment. I have a pretty good stash of ammo but I like the I did it myself feeling. Will I save money? Probably not but I enjoy it. Plus I load .32 S&W long which is kind of an obscure load nowadays.
On another note for those contemplating it, RCBS has an awesome rebate going on now, spend $500 and get $175 rebate, so you could get a Rockchucker starter set( which is what I went with), with a couple of sets of dies and a few odds and ends for a great price.
