After the Seabreeze ATS that are being made in small numbers in the UK I stumbled upon another small manufacturer in Guernsey making waterfall ATS's. The guy makes 3 sizes but can also make bespoke ones to your requirements. Here is his Video on YouTube.

I spoke to him recently and he is currently doing a few mods and tweaks to the design to improve it even further. Unlike with the Seabreeze, he does not sell on eBay just directly to any interested customers. His prices seem very reasonable when compared to the opposition.
