I really appreciate your willingness to be the one to take the leap of faith, and I wish I could reward that by buying this reg. Unfortunately, I spoke with my LDS and learned something which I assume you thought I already knew. I knew the Oasis was made back in the 90's, discontinued for a bit, and then a new model released. I kind of thought the part kits were interchangeable, and called the my local Sherwood guy to confirm that. He has told me the part kits are not interchangeable, and that, while the old oasis parts are still available for the moment, there's no telling for how long. Given that I've just started out in diving and am trying to buy gear that will last me a while, that's obviously a concern for me, so I'm afraid I'll have to pass. Sorry.
