i have played a little with magic loop, but i end up with a tangled mess!I took a magic loop sox class at a great yarn shop in Hillsborough, NC and then figured out how to do two at a time.
I much prefer doing both socks together so that I don't have to count rows or stitches to ensure they are match in size and shape. Also, I don't end up with just one sock.
A friend, who no longer knits, just gave me a huge bag full of sock yarn, including lots of lovely hand "painted" yarns!! Woot !!
