Nice machine!
How old was that Altendorf? You can buy a secondhand Altendorf, couple of years old for the same price as that Robland new. And if was up to me, I would buy the used Altendorf.
I think you get more bang for the buck.
As for the Martin, I have a Martin T72A from 1997 bought it 6 months ago for €5000. Digital readouts, automatic height and blade tilting and an automatic fence, great machine!
So maybe in a couple of years you can get that saw from your wallpaper secondhand!
