I suggest that you need to first find out if you even like reloading . I know folks that went out , spent hundreds and hundreds of dollars , sometimes close to a thousand only to find out that they didn't like it after all . Then sold it off for a fraction of what they paid for it . Some of those above suggestions will cost you a lot of money and you haven't even pulled the handle yet for the first time . I strongly suggest you start out slow , even work at a friends house for awhile reloading , get the feel for it , see if it's what you really want to do . My reloading started out with a Lee Classic Loader Kit , you can hold the complete kit in the palm of your hand . I set a goal , reload 1000 38spl 's before I move up to a press . I learned a lot , I mean a lot about the process of making good reloads . A lot of people will be quick to help you spend your money . Spending a lot of money right at the first doesn't make you a good , competent , safe reloader . In the end , it's up to you . Good Luck
PS . I know of a fella that has a Dillon 550B and the Dillon 650B , sitting in his garage , just collecting dust . He listened to a lot of folks , spend a ton of money and then decided he doesn't care for it . He and his wife ride dirt bikes together out in the country .
