Like all Milwaukee stuff, it's kind of confusing when you search as you get a million results. I bought their 3-in-1 1/4", 3/8" and 1/2" kits.
They bundle the 1/4 and 3/8 for $289 if that interests you more. They bundle the 3/8 and 1/2 for $409 as well. Seems like you get enough of a discount that buying all 3 together for $499 made more sense. I hate to pay that much for socket sets but this will suit me a lot better than what I've got. I will have to be more careful about not misplacing them though. Keeping them in their trays in my toolbox should help with that so I'm not carrying the case around the garage, dumping it over and they all fall out, etc. Grab from the tool box and put back when done.
