I Totally agree with Rick.
The Dive-Rite system is a good option.
I bought a DIN Left and a DIN Right for my Al 80's. put the plugs in and used them both as singles.
When it was time to start using doubles, I just bought the center piece. and had a ready to go set, that could be used as singles again in a matter of minutes.
I could also have bought a H adapter as well and had any combination.
Call them up, they are very helpfull.
Its by far a cheaper option that the Y valve, which is a specific "one time use" item.

Hundreds of thousands of dives are done every day without H valves or bp/wings. IMO H valves are ridiculous. If you're in a situation where you feel you need an H valve, you should be diving doubles. And doubles are NOT the same as having a pony BTW.
Also, the Buddy BC appears to be a very quality product that has served the Brits for many years Perhaps YOU should broaden your thinking instead of slamming pescador for what are very reasonable remarks.

I also forgot to mention that one of the reasons i want to goto a y or h valve is that hopefully i will be diving doubles shortly and would like to keep the same reg set up to go from doubles to singles without having to change change all my hoses and regs to go from double tanks to single tanks.Keeps everything standard.

Heres something for you.A double rig set up with a pony.....hehe

Why?
Let me give you a specific example where we use single tanks with "H" valves - spearfishing in 130'. Short dives, so there's plenty of gas in a single tank, but below the safe CESA depth - and since we're spearing we are not so unrealistic as to believe we can always maintain buddy integrity. Therefore redundancy is dictated, but not more gas. Doubles are neither required nor desired for these dives - they would be a major pain in the boats we use.
Another specific example - any single tank cave dive.

Any Cavern Course requires dual orifice (Y or H) valve tank (71.2 CF minimum). Two (2) single hose regulators, one with a 7ft. hose, SPG, octopus second stage and power inflator for BC
You can use a single tank.
Right or wrong, thems the rules.

In what way is 130' recreational dive too deep for a CESA using a single tank with single regulator set up? (I don't want to get into why I think 130' spearfishing is a really a 150' dive.)
I don't agree with single tanks in an overhead environment.
IMO - I disagree with the idea that a pony is insufficient as a redundant air source in recreational diving for several reasons.
1. Of all the stories I've heard in recreational scuba about switching to redundant air it was simply a matter of needing enough air to reach the surface - to buy a few minutes. Most pony bottles buy you this plus much more. (Clearly more gas is required for technical diving and overhead environments).
2. Heavy. Requiring other special compensations, including possibly more lift than standard recreational jacket style bc's may offer. Or assistance might be required getting into or out of a boat if you are not strong enough for this much weight, as could be the case with some out of shape men and many women divers. Transporting between auto and boat or beach. Harder on spine and body.
3. More expensive, including special valves, and other special rig accomodations dual tank bands, bp, possibly wings.
4. Special equipment, valves, etc - involve more technical training.
5. Larger profile. More difficult to manage for newer divers. More difficult in smaller spaces - such as the trunk of a car.
Now I know there will be disagreement with this post, because many of the DIR and GUE folks do plenty of rec diving on their rigs. And these individuals wish all divers would learn their methods and own their equipment. But the general industry has not adopted this format or equipment. Though change is a good thing, for the reasons I mentioned above, adoption is a long way off if ever. And from my personal experience technical rigs scare away newcomers to diving. I personally think tech is cool, but have also spoke with hundreds of new divers, and I understand their reservations.
In my opinion a recreational diver should have a redundant air source ... but a pony bottle is sufficient for this purpose. And I also agree that twins and tech rigs have a solid place in recreational diving.
