The thing to remember is that you may not take to it, once you have had a go, therefore if you are saddled with hundreds of pounds worth of kit and you are going to suffer a bigger loss than had you started with a more modest kit. I always recommend to people to go with a Lee kit, it is moderately priced and with the exception of calipers and dies you are good to go. You can always go upmarket if you feel the need to.
I started with a Lee kit and still use a lot of it now, I have acquired lots of bits and pieces in other brands and my kit is now a real mix and match affair.
I would stay away from the "four hole" type kits, unless you intend to load in mass for pistols. You will not feel the full benefit of improved accuracy or attain consistency if you go this route, in IMHO.
It can be very confusing, try to find someone who reloads that lives near to you and see if they will keep you right, have a look at their kit, see what is needed, how much time is involved, how much it will cost, how much do you shoot, is cost a consideration, do you want to go down this road for the interest and hobby aspect's alone, go enjoy
