I have a limited number of parts for all of the Tekna regs along with all the specs and have worked on them for 20+ years. I have a metal body 2100 right out of the box that I'm saving for a show piece. They work great as long as they're serviced right and you have the right parts, which I do. You can contact me at scubarepairexpress@gmail.com and I can make arrangements to get the regs here, get them serviced and back to you.
