I've owned some Lee equipment over the years, some of it I liked and some of it was crap. I very much like Lee's Factory Crimp Dies, especially for straight wall pistol cartridges. The little C press they market I found very handy for priming and bullet seating, but it didn't stand up to resizing full sized rifle cartridges. Never the less, these presses are good if you want a small low cost second press on your bench. The newest version of the hand priming tool is no where near as good as the original one which required putting the primer in the shell holder by hand, yet the press mounted priming tool I thought was quite good.
Lee makes one product which I consider dangerous unless they have improved it since I owned mine, and that is their scale. The first time I saw this thing I thought the design was great. The beam would weigh a maximum of 100 grs rather than 500 grs which is the industry norm. This should result in a far more accurate scale. But not only was it less accurate, it would stick, and no matter how many times you bumped the pan, it was difficult to get the same measurement twice, and when it did measure the same weight twice, you had no confidence that the weight was true. Sometimes the measured weight was off the true weight by several grains. I'm surprised this thing is still being sold.
My standard advise is to suggest that you purchase as many manuals as you can. As you gain experience you will find that it is useful to get data from more than one source.
When it comes to reloading tools all manufacturers are capable of making good products, and all have had stuff fall through the cracks. I prefer RCBS to most other stuff, but there are some things that the other makers do better. I have gear by RCBS, Lyman, Redding, Wilson, Sinclair, Lee, Giraud, and some I've made myself. Start with a beginners set from the manufacturer of your choice - I believe the best value is RCBS, but other folks have different ideas. I would not purchase the Lee set if that ####ty scale is part of the package. As you gain experience you can begin to add the tools you discover will make your operation more efficient.
