As been mentioned trying things out is important, as well when you are out diving, look at what others are using, common brands, models etc. Also think of where you want your diving to go and be sure the regs you buy will suit that. I have seen people by inexpensive warm water regs, only to have to purchase again as they upgrade. I personaly use Scubapro MK25 first and the S600 second. I dive cold and deep, and in the winter and have never had an issue with the regs. As someone said to me, there are lots of things you can buy inexpensively, but do not cheap out on regs, spend the most on them, they keep you alive.
