Actually, Diving Concepts makes a very excellent ring system themselves that many of us prefer (and, IMNSHO, is better designed than the Viking Bayonet system...) The Diving Concepts dry glove rings are a little costly for the rings, but replacement gloves are $3/set. Changing them, once you know how, is a five minute job. The rings just snap right on over your wrist seals, leaving you with a wrist dam in place in case of flooding, or you can remove the wrist seals and cement the rings to your suit instead.
They glove side just "snaps" on (press-fit with an o-ring seal) and pops off easily when you want to remove them. I've never had them flood in 5+ years, other than from a punctured glove, or my own stupidity in capturing the thumb loop from my undies in the joint.
Alternatively, if you like more dexterity than smurf gloves, Deep Sea Dry Comfort neoprene gloves are about $35 a pair online, and they have inner gaskets which can also be mounted onto most ring systems. I actually prefer the neoprene dry gloves from Deep Sea, as they're warmer and I find I have more dexterity with them. A set lasts about a year for me. Not nearly as cheap as the smurf gloves, but more rugged...
