ngzhang offers great customer support and Icarus boards have the highest resale value compared to X6500 because there are many available IO pins (80-100+), not to mention chip interconnection paths.
Also his design uses 100% solid state capacitors which is good for longevity.
* I'm not implying that X6500 is bad, just pointed some pros of Icarus.
Just an another example how chinese made stuff can be of amazing value

But yeah, one could use that board for something else too
