The Lee is a good machine, if you have the model that feeds the primer automatically; if you have to place each primer separately, it is not that much faster than a single stage.
When I was into Silhouette, I would always use the single stage, it makes more consistent ammo.
Now, if you are reloading SD practice rounds, and if you can afford it, get a progressive. If you catch any kind of bug, like IDPA or others, you'll be reloading a lot more than you plan now
