A "forgotten" Thorens is the TD-150AB (A for arm, B for base). It’s design is the same as that of the AR (low-mass floating subchassis), but German/Swiss vs. U.S.A. made. The arm on the 150 is FAR better than the one on the AR XA/B. I don’t know how much they are going for.
One thing of interest in the AR XA/B is that George Merrill offered a drop-in replacement for the table’s stock subchassis and platter, greatly improving it’s sound and allowing the use of an arm of one’s own choice.
I replaced my AR ES-1 with a VPI HW-19 Mk.1, which I much preferred. A Mk.1/2/3 can be had for around $500, and is a pretty darn good table.
