I just got a message on one the the acting sites I am apart of about a new workshop that is offered here in NY. Well, it's new to me!
Anyhoo, its taught by actor David Vadim http://actingreacting.com/technique and I thought it was an interesting class. Its 4 consecutive Sunday Sessions, $220, for 1.5-2hrs depending on class size. The workshop is suppose to help you go with your natural instinct and help you to create your own unique techinque.

May be worth a try!
