I just came across this thread and would like to make an observation. The Scorpion exo900 that I purchased in Septmber/14 was purchased at a clearance event not far from where I live. I had been watching and comparing for some time and was waiting for it to go on sale as I had discovered it is a discontinued item. It is replaced with the exo900x which is advertised as fitting a different head shape.(This info taken from last years memory bank and is subject to errors and omissions). You may decide to check out the new Scorpion if you were satisfied with the finish of the prior.
