The short answer is, "that depends"
What are you going to reload?
How much are you going to reload?
If you want to load lots of pistol stuff your going to want a progressive press.
If your doing small numbers of precision rifle ammo. a single or turret press is in order.
I would suggest you stick with whatever your dad has to maintain continuity.
Most mfg offer kit sets for whatever press you decide on.
And lastly, if you don't like loading on what your dad has, you need to shop around
