I was just in my local dive shop picking up a few things for my upcoming trip to Nassau. I am in the market for a new reg and was considering the TX100. As i was drooling over it the salesman pulled out the newest reg from Apeks the ATX200. The price he gave me for the TX100 was $550.00 and for the ATX200 was only $70 more at $620. I have not seen any reviews for the ATX200 yet. The TX100 is well known and comes strongly recommended. Does anyone have any info on the ATX200? What is the difference between the two?
