Home depot carries the sharkbite brand, lowes has gator grip or something like that, they are the same exact thing. The 1/2 - 1/4 comp shut off may be hard to find at either of those places, I order mine online.. I know they sell a 1/2 - 3/8 shut-off, and you can buy a 3/8-1/4 reducer to screw on the end to adapt to tie into the water line. Or you can buy a 1/2 -1/4 shut off that you sweat in. I prefer the least amount of connections, and the least amount of time, thats why i use theses fittings. They do cost alittle more, but my time is more valuable.
