Moses foils are very popular among many of my kitesurfing friends. They are very well engineered, well made and have a broad range of wings and masts for different applications.
There are quite a few foils with good prices from China. The designs and quality vary widely. In many cases, it is hard to know what you are actually getting because the pictures and advertisements are poor quality. Some of these are sold as samples, with the hope or expectation that you will potentially order many more units. So, I wonder if some of these are more like prototype units? So, if you have a confirmed product from China (e.g. someone has bought that same product and recommends it) in many cases the quality and value (and maybe the design, too) can be excellent. Some of these are knockoffs of marketed products (perhaps made in the same factory as known brands).
