guys, cut the dude a break. 0-24 dives, new to the sport, and you want him to buy a Shearwater ($$$$$)...... fabulous, but.....
My advice - get a budget level nitrox capable (likely just about all of them are now days) unit that has gauge mode, and dive it to your heart's content. Should you go whole hog later on and venture into some advanced diving, you can use it as the "required" bottom timer/depth gauge, and evaluate other options then. Done for <$300.
Sometimes I think you guys do this to new divers to get the used market flooded with more high end stuff when folks find diving is not for them....
