I need a new calculator. I always wondered what the M buttons on a calculator were for, and today I finally got around to Googling for it. Pretty cool.

While watching videos explaining various calculator buttons, I found that some calculators have a 2nd button and a format button where you can set it to AOS and it gives you the answer to the problem using the order of operations, so no M buttons needed. So, it seems to me that the latter type of calculator does what calculators with M buttons do, is that correct? Just wondering if one is more useful than the other when needing to do problems like the following: 6x3 - 2x7 + 15÷5 or 1000 ÷ 1.07 to the 4th power.

Not a very expensive life decision, but I want to make sure I get the best type of calculator. I don't do anything too complicated, just basic record keeping (usually). I've got two desktop calculators picked out, one with each type of set of buttons.
