You got 3K? If that's the case I'd look at how many rounds you are going to be shooting. The 1050 is for serious quantities per month and it's not easy or cheap to swap calibers. That said if you are shooting more than 1 to 3K per month in a single caliber then the 1050 is what you want.
Otherwise get a XL650, Brian's "the way it should be" upgrades, a RT1200 trimmer set up for .223 and a Redding T7 Turret press for working up loads, small batch and rifle loading. You will eventually be doing loads on a single stage at some point and you might as well get the best. Then get the scales, calipers, manuals, etc. You will still have some cash for components. Brian has a great explanation on his site and also some info on the approximate wait time it's well worth checking out.
