Is a cable cooker worth it?

I have heard many good things that a cable cooker can do to improve a system, but I am wondering at what point the expense of a cooker is worth it? Alltogether, how long must I burn in my cables, via system play, before they are good and hot as opposed to the expense of buying an Audio Dharma cooker and having near instant results? I don't know where I fall in terms of mid to high end audiophile, but I calculate that by the time I get all the components that I want for my system, minus cables and extras, I am approaching $8500 bucks(only components). So, is a cable cooker worth it for someone like me?
