Hey Greg,
Welcome to Rebreather World, like Rob say, this is the most friendly discussion board actually (this is my point of view).
Everyone here is willing to help and share his own experience and if you think about it, sometimes (the true is all the time) experience doesn't come with out expenses and here everybody is really helpfully.
I hope you enjoy the Rebreather World.
Cheers,
Mike -
