| Enough of my flippancy (oh yes, did I mention I'm divorced, so it's wasn't great advice).
There is another option:
Why manifold? Why not have two independent cylinders, that way all you need is the bands or something like the buddy twin-cambands. I know a few divers that have said manifolding wasn't necessary (I know this is going to get a lot of comment!!!) - some have suggested two independent cylinders with different air mixes. You could save a lot this way. That would make upgrade from a single to a twin a lot easier and you can then also have a flexible system so that you don't look a prat doing a shallow bimble on twins - just use one of them.
