The LoadAll does fine for low volume reloading. I've got a couple of them, and they do what they're supposed to do. Nothing else to buy, they come with a full set of bushings.
I also have quite a few MECs. I just never pass one up if the price is right and the mood strikes me. With a little looking around, you can find a used MEC for the price of the LEE unit. I shop craigslist.com, just picked up a MEC Sizemaster for $50, a 600jr for $40 and another 600jr for $35, all in top condition. As pointed out, there are a lot more adjusting involved with a MEC, but they are a better press.
The LoadAll will probably do what you need, but I'd look around for a deal on a MEC. Just a thought.
