Let me start this post off by saying this is solely my opinion, and you know the saying about opinions.
Lee Load All: A good press to get a feel for loading shells. You will fight it a good bit to get crimp height right and you need a new press for every gauge. I used one for about a week before I said "there has to be a better way." This press is not designed to load new hulls. Basically a hunk of plastic.
MEC presses: Much higher quality than the Lee Load All's. Can be a bit finicky on adjustment. The factory crimp starters are junk, get the upgraded version BPI sells. This press is not designed to load new hulls. Will need a new press for every gauge.
Italian Presses: Companies like OMV and Gaep have produced a small press that gives us the "factory style crimps" we are accustomed to on new ammo. It is important to note that these machines are designed and built to load new hulls. They have a initial crimp station, a ribassatore crimp station, and a final crimp station that is rotating at 900 RPM to apply the factory rolled finished to the fold crimp. The machines are easy to configure, I load everything from 410 to 10 gauge on mine.
The Italian presses provide crimps that are beautiful. I can change calibers and adjust the press in less than a minute. However, they are not designed to be a "reloader." There is no station for depriming or resizing, though they do sell a handy little contraption for that process.
If you are going to be a non toxic shot loader chances are you are going to be loading mainly new hulls. If you are a trap shooter you are likely going to be re-loading fired hulls. I would buy the press that suits your needs best.
Here's a few 10 gauge shells from the other day:

And some 410 on the same press: (ask your buddy with a MEC if they can do that
