I know a few people here, such as myself, got started with tracksaws via the EZ smart / Eurekazone projects. There are also several refugees from the t-saw forum. It looks like that forum has shut down and upon checking the Eurekazone site, I found a note stating that the company ceased manufacturing operations December 15, 2019.
Sad to see it go. There were a lot of promising ideas that were never fully realized... Their Facebook page has some comments stating that they will sell some stuff through Amazon in the near future.
