For anyone considering an AR table, look for one from the 1980's, the ES-1. The 60's model has a terrible tonearm, the ES-1 could be had with no arm or a Jelco-sourced (I belive) one.
I have had three AR's, starting with the original back in 1969. In the 80's I bought one and cut the arm "housing" off the floating subchassis, mounting a unipivot in it's place. It worked okay, but when AR introduced the ES-1 I got myself one (and mounted a Rega RB300 on it), and liked it even more.
I then discovered the VPI HW-19, and the AR was history.
