I just thought it would be fair to note what they have now done for me, given the detail with which I went into their shortcomings previously. I've replaced the saw with a Sheppach, and am very pleased with it (it cost about the same).
It's the Basato 3. It is so well made it was a pleasure to assemble and set up - the very first cut was perfectly straight and square and so have been all subsequent ones.
