Ive been using one similar to Double/Longtail/Continental cast-on with the exception of bringing the further side into the left loop. Ive found this method produces neater looking edges and you do not need to necessarily do a purl row after. But this method is tiring and hurts your hand after a while.
Ive also tried the Double/Longtail/Continental on this site but the results uneven and messy. This might be because I'm not used to this cast-on but I'm getting really annoyed.
