I just bought an Apex xtx50 with the DS4 first stage. They also offer the free octo, however its the egress oct. I "upgraded" to the xtx 40 octo, They credited me the egress price wich left about 50 dollar difference I had to pay. If memory served me well the 100 and 200 come with different first stages. One the FRS and the Other the FST. I asked around, and no one could state a glaring difference in breathing. I was told the 200 would handle tri-mix and deep water, over two hundred feet, better, but if your not into that it may not be worth the price difference. The xtx50 with the ds4 is cheeper than the legend. Only difference in second stage on the 50, 100, and 200 is cosmetic.
