I started with all LEE products and over time upgraded almost everything to better quality. That being said, I have shot some of my best groups using LEE dies and a LEE Challenger press. If you plan on loading .223 and .30-06 as well as .243, you might want to look at better gear.
I think the LEE kit works great for someone who may only load 1 or 2 calibers once or twice a year.
The LEE perfect powder measure works much better than others with stick powders but tends to leak with fine ball powders. If you get the kit, the manual will have loads in it shown in (cc) cubic centimeters as well as (grains) weight. You can set the powder measure according to the scale at say 3.4 cc's, (there is an adjustable thumb-screw type scale on the LEE powder measure), and verify with the scale or adjust accordingly. That being said, I don't like the LEE scale at all but it works.
The chamfer tools work fine and the LEE cutter with separately purchased, caliber-specific case length gauges, is probably the most cost-effective reloading tool I have ever seen. It really works well and if you have a drill motor you can speed things along quite nicely.
I have the older style LEE hand primer and can say it works fine. Just be careful to point the tray away from your face while seating primers and wear safety glasses. They don't have a bad reputation but safety glasses are cheaper than ER bills.
If I had to do it all over again, I would buy another LEE anniversary kit, set of .243 dies, a dial caliper, and a .243 case length gauge for the LEE cutter.
Throw in 1 box of 100 grain bullets, 100 primers, and 1 lb. of H-4350, and I would be cooking with gas. Take care and good luck.
P.S. If you want to check the calibration of your LEE scale, try weighing one of the new bullets on it. It should be close enough in advertised weight to dial-in the scale properly. If it is off by .2 grains or so, that won't hurt a thing. Stay prudent and work you loads up from a safe starting point.

243 Winchester 100 grain Speer BTSP bullet 2.650" OAL H-4350 Powder
Start load: 37.0 grains 2806 fps
Max load: 40.0 grains 2973 fps
I would load the following:
(3) rounds at 37.0 grains
(3) rounds at 37.4 grains
(3) rounds at 38.1 grains
(3) rounds at 38.5 grains
(3) rounds at 38.9 grains
(3) rounds at 39.3 grains
(3) rounds at 39.7 grains
(3) rounds at 40.1 grains (OVER MAX)
I would setup 8 different targets and shoot them all in order. One round from the first load at the first target, then one round from the second load at the second target, then one round from the third load at the third target, etc. I would shoot 8 rounds, one of each load, at 8 separate targets, in the order of powder increase. It is important to pay attention to pressure signs and take a note pad. Label the rounds if you can with a sharpie or something. Once you have shot the first string (8 rounds) you should have one hole in each target. Then start the second string from Load 1, target 1, then shoot Load 2, target 2, etc. Eventually you will have 8 targets with 3 holes each and have a real good idea which load you like. Then it is back to the bench to load up your favorite load.
You could skip all of this and just load at say 38.0 grains, 39.0 grains, and 40.0 grains, checking for pressure signs and all, but where would all of the fun be?
These rounds have a 1% increase in powder in each stage. For a larger case, 30-06 +, I would use a 2% increment in powder.
