I have an SR1 and I have about 150 dives on it and I love it. But they are fussy. When you turn your air on, you need to put your thumb on the top of the first stage to provide a bit of extra resistance to the piston. If you do that you are fine. If you don't do that, 99% of the time you will be fine, but every so often something will pop inside the first stage stage and it is back to the repair shop (sorry, I can't give chapter and verse on the mechanical bits). Other than that, it is by far the best reg I have ever owned.
I also have a couple of Sherwood Bruts. Great workhorses (and easy to maintain), but not an especially smooth breathing reg, and not one you would want to take too deep.
