I, too, use a Lee Load-All II, and like it just fine. It's not the fastest machine out there, and there's an oil-field's worth of plastic in it, but it loads good shells with minimal effort. What I've done, as a low-volume reloader, is to find a recipe that works for every hull I have.
With the bushings I've got, in my press, that's 18 measured grains of Green Dot and 1 1/8 oz of #7.5 magnum shot. For the Winchester and Remington hulls, I can use Winchester 209 primers in both, per Alliant recipes. For the Federal maroon hulls, I just use Federal primers. Don't trust the Lee Charge Table, use a scale. Mine throws charges that are noticably lighter than the table shows. TO get the load I wanted, I had to go up 2 bushings from the table value. Yours will likely be different. They're quite consistent within themselves, but they probably vary quite a bit from unit to unit. Wiegh your charges until you know what the press is doing.
As to the cost factor, I'm loading what is an 1 1/8 oz, hard-shot, premium load, for around a buck less per box than the 1 oz promo loads... which I can't hit very well with. Switching to a 1 1/8 oz handload produced a noticable improvement in my scores at the range, in a soft-shooting load that doesn't dirty up the gun any worse than the cheapies did. In 3 weeks I'll be able to tell you how they work in the field, but I've got no worries.
It's worth it, and it's fun to boot.
