First of all the TX100 is discontinued and APEX is just getting rid of extra stock. But they are still a great reg. As far as your Zeagle question that I don't think has been answered... Zeagle regs are made by zeagle. According to the manufacturer they are not the same parts, however, if you look close they are. The thing is that Zeagle used to make Apeks BCD's and Apeks used to make zeagle regs. Now zeagle makes them for themselves, but they are still very similar to the apeks in all aspects. Cost look and performance. Even the first stages are simliar. As posted elsewhere, the only difference between the 50 and the 200 is the port design of the first stage that can be noticed at depth by some.
