If you can't afford it don't do it. If you can afford it learn from the best only.
Right now I would say Max from RSD is the best coach out there and for good reason.

I learnt more from one weekend going out with a Pro then a years worth of watching and reading. You can only learn so much from materials. You can only get as good as your ego is willing to let you.

An real instructor will push you harder and beyond what you thought is possible.
