stretching machines are a waste of money unless you're just impatient and have the money to throw away.

Just discipline yourself to do it naturally, you don't need a torture machine. There are many different routines for stretching, a 5 second google search will get you good ones (will dig up links later).

Machines only take you into the side splits. They don't work any other stretches. the ideal way to do it is to work everything gradually up to the splits. you need hamstring stretches, quad stretches, butterfly stretches, groin stretches, hip stretching, and work on all your splits, not just the side splits.

get a machine if every thing you try blows up in your face, if you have the money, and if you don't mind only being able to do side splits and nothing else.
