I am just finishing up my advanced nitrox course tomorrow. Lots of gear reconfigurations. I am going to start diving doubles soon and get used to them before I take my deco course...Both from TDI. So I am getting ready to purchase 3 first and second stages for the doubles and a stage. My instructor suggests the Scubapro Mark 25 series. A very trusted LDS owner in Upstate NY suggests the Zeagle Flathead series. They are both in the same price range and I know they are both good regs. I'm looking for input for any info from members who may be able to help me make a decision. I don't think I can go wrong with either, but I'd appreciate any input that may help. In any event...I'm getting ready to spend some serious money. They say boat is a hole you throw money into. Kind of relates to SCUBA. The more training I get the more gear I find I need to buy...:shakehead
