My son is now doing general contract work and he is asking for a cordless circular saw for Xmas. I found 3 that I am considering, all Milwaukee and all the M18 (he already has a lot of tools in that line). The three that I found are: 2631, 2732 and 2830. I am leaning toward the 2732 but it's not entirely clear what advantage the 2830 provides. It's $20 more but from reading the specs it doesn't seem to have any real advantages except for the physical shape of the tool. If anyone thinks the 2631 would be fine, I'd like to hear that as well, but my thinking is that since he'll be using this tool all the time better that he get the best tool for the job.
