I don't think RCBS is of the same quality it once was, but it is still very good. I'm almost 100 percent RCBS, but Hornady seems to be giving RCBS some serious competition. If you can find an older RCBS Rockchucker, these are very good presses.
The ability to use 1-1/4" dies isn't important, unless you need to reload .50 BMG. However, presses that support 1-1/4" dies tend to be much heavier than those which don't.
I wouldn't be too concerned about an electronic scale, but you're right that a good beam scale will last several lifetimes.
I guess I didn't give you much information with which to make a decision. I do have a very strong opinion about case trimmers, though: The only case trimmer worth having, in my opinion, is the L. E. Wilson trimmer.
