OK, folks, what is more dangerous, doing a homebrew or taking deepair 
instruction from a TDI instroketer? I think the facts speak for 
themselves.

You know, Ted some people also purchase guns and blow their heads off 
jumping over a fence. This is not about doing it cheaper, it is about not 
having to be forced to do deepair to get to trimix. Do you offer 
instruction on trimix with the deepair crap?
