Lee is the bottom price equipment. Just like the bottom price car it will perform within its design parameters but if you want to race you have to spend more money. I started loading with the Lee Loader kit in a box - they call it the "Classic Kit" now but it was about the only thing Lee made back then. (Yes, I loaded my own to hunt dinosaurs) I loaded for two guns then; a 357 Mag and 30-'06. The '06 got sub MOA accuracy and I still have the kit. The 357 gave me some good practice shooting and honing my skills but not the best accuracy. I still have the kit. I used those old loaders with an arbor press (for pushing bearings) instead of a mallet because I kept firing off the primers when I used the mallet as suggested.
My first press was a "Rock Chucker" from RCBS and it lasted for years until I started swedging bullets and it still works but I had to machine it out for needle bearing due to the high pressures of bullet making and the wear that occured. It wasn't made for making bullets - it was made for sizing cases. I have a total offour presses now and one of them is a press by Lee. I got it from my brother who used it to try to make 6mm TCU cases and ended up with a bunch of bent cases - they bent near thebase junction due to flex in the press. I use it to make practice rounds in 38 spl for my 357. It does a fair job when just neck sizing the straight walled cases with a carbide die. I personally don't think it is adequate for doing anything else. It is, after all, a bottom line KIA and most of my other loads I want more from then that. I am an accuracy freek - if it won't stay inside 3/4 MOA it needs work. I have a 358 Win that shoots sub caliber groups with one of its loads and half inch groups with the other (hunting) loads. My old '06 and 257shoot well below MOA and my 30-30 stays below MOA (single shot - not lever). My 357 Maximum shoots sub-MOA all day long and my old 357 Mag shoots like any revolver with 25000+ rounds throughit at about 2 MOA - (used for two years in Hunter's Pistolcompetition)I keep shooting it because it is my carry gun and I trust it.
Bottom line: If you want a press that will hold up to reloading for your lifetime then invest in good equipment. If you want to have a press that will just barely meet your needs for now - investing about a third of the price of a good one then get the KIA (Lee) kit.
