Hog Regs are deffinately the most bang for your buck! Not a fan of piston regs of any brand, but the HOG BP2 and EDGE Extream Titanium regs compare directly to the atomic regs for a fraction of the cost. I personally dive with HOG D1CW and D2CW wich i love! Solid regs for cold and deep diving. The D2 is real low profile and the D1 is flexible with a swivel and 5th LP port out of the bottom for ease of routing. I could go on and on about these regs but the name says it all; Highly Optimized Gear! The only drawback of HOG (not EDGE) is they only come in DIN, but easily remedied with a din to yoke adapter or a yoke conversion kit! I'd recomend these regs to everyone from entry level divers to extream DECO divers. Dollar for dollar these things just cant be beat!
