I have the Lee hand prime tool & the press mounted Autoprime II tool. I prefer the press mounted tool, as the hand primer makes my hand sore after priming 100 or so cases. The hand prime tool requires it's own shell holders. The press mounted primer uses standard shell holders. I haven't had any issues with either tool.

I also have both. Both have their place. If I am only going to do a few quick (20 or so) I will use the hand prime. Usually I do things in batches of 400 (that's what my tumbler holds). I will clean 400, then clean 400 primer pockets, then inspect 400 with a lighted magnifying glass, then length trim, then prime, bag in 100's with dessicant until I am ready to load them.
This usually takes me about a week of evenings, sitting around watching TV for a couple of hours. I do about 400 a month. I currently have a few thousand of various calbres ready to go at any time.
I love Lee stuff for the most part. There are better products out there and I have them if I didn't like Lee's, but ALL of the Lee products do what they say. Load ammo cheap.
I, also, have a mixed bag of tools, depending on what I need to do. I used to set up 2 challenger presses and my RockChucker to do what I now do with the Lee Turret press.
Carry on, their stuff works and you can replace/upgrade as you decide something is better. However, if you have a buddy with something, borrow it and see if you actually like it first.
