I am shopping for my first reg and it has my head spinning a bit. I plan to dive in cold water usually to around 60 ft. I want something that won't breathe hard because the few rentals I have tried that were hard to breath off of drove me nuts! After countless hours on the internet and some time in LDS I have narrowed it down to 8 models...okay so that isn't so narrow but I'm getting there I would love to hear any complaints or reviews on any of these. Right now I am leaning toward the Apex series but still have an open mind. Take my poll too! Thanks
