First, let me say that I am stubborn as a mule, so I'll probably hold off of M12 stuff forever if I haven't caved by now even if they're every bit as amazing as people say.
That being said, I agree that there are some useful tools, I don't care for accessories (clothing, speakers, etc.) and most of those items have M18 equivalents (most of which I own) or I have significantly better non-Milwaukee equivalents (like my Hakko soldering setup). The underhood light is probably the thing on that list that I'm most bitter about there not being an M18 equivalent. I've held out this many years without getting one though, so I can't see that changing now.
On that note, I saw mention of a bunch of new (M18) ratchets. Is there somewhere that has a definitive list of all the M18 ratchets (3/8" specifically) and their stats? I generally prefer to hand tighten most of my stuff, but having the ratchet would be handy now and then, especially for some of my more repetitive work or on things with longer fasteners. I have air ratchets but never bother with them - hate air lines!
Also, what's the most recent 3/8" M18 impact? Preferably the stubby impact.
I know a lot of new tools got released recently so I want to figure out what's the latest and greatest and if it's worth buying the newest ones or trying to find a deal on what is now the previous gen.
