Folding sinks and things

I'm still on the hunt for a decent quality folding boat sink that does not cost an arm and a leg. These pictures are just some that I have found on the web. I like the look of the top one a lot, it seems to be a stainless steel complete vanity station which came from an old train car, and could be good in the right boat. The bottom one is meant for RV's and shows the sink before the mixer faucet and drain have been added. It's called the Cleo and seems to be available in Europe but as far as can tell is not available in the USA. It's closer to what i was looking for but does look a bit cheap and plasticy. With the interest in tiny houses I feel it's only a matter of time before the right thing will turn up. The search continues ........
