Beware the Dive Rite DIN-to-yoke adapter. I own a couple of them. On a recent vacation to Bonaire, my girlfriend and I encountered an older Sherwood yoke tank valve that really didn't fit well with the DR adapter. The problem was the piece on the adapter that interfaces with tank valve -- it was just barely small enough to fit into the yoke recess and compress the o-ring. We had a hell of a time assembling the reg/tank before the dive. It usually took 3 or 4 tries to set things up without getting a noticeable leak. Then, after the dive, the assembly was prone to getting stuck -- we had to "rock" it from side to side to detach the reg from the tank. I notified DR about this problem. They acknowledged the problem, although they did not say that they were planning any design changes. (I found that very surprising!) DR probably hopes that people will eventually stop using the older Sherwood tank valves.
On the same trip, one of our dive buddies was using the "generic" Trident DIN-to-yoke adapter. He likes it, and it seemed to work well on all of the tank valves we encountered.
For what it's worth, the DR build quality is very good -- sturdy metal that I know will last a long time. Despite our issue in Bonaire, we have continued to use the adapters on several local boat trips and trips to Catalina Island...and the DR adapters have worked just fine. Just know that when you go to Bonaire (or perhaps some other remote destination)...they might not work so well.
Make sure you also buy a cheapy rubber stopper with your adapter. It will come in handy if you don't want to remove/replace the adapter after/before each dive.
Have fun and dive safe.
