Buy what ever you feel comfortable operating and what makes your ammo the best for you. I personally love Dillon and Redding equipment. it does not mean you need to get these, just that these brands make me the best reloader I can be. there are all different grades of dies, presses, and equipment. find out what you like, how you like your press to work, the features you like, can't live without, and even the orientation of the action. all things you need to put into your spending money. I have run through and sold over $10,000.00 worth of equipment before settling on the combinations I have for different calibers. I am a Dillon guy, I like the versatility of the RL-550's. I have friends that will not touch the RL-550 but they love the RL-650. I have a Dillon RL-1050 for high volume ammo for my 45 ACP, 9MM and 38 Super. that is all that press loads. but it does it so well and fast that it is worth having. the RL-550's I have load everything else I shoot and my friend's shoot, and some of my clients that come in and use my equipment to load their own hunting and target ammo.
the best thing to remember, this loading equipment is yours, it will serve you. Make the experience you have loading as easy, pleasurable, and as intuitive as you can make it. Accuracy will follow and make your ammo better than you can ever buy.
