Tonearm Suggestions

I have limited knowledge on tonearms and need suggestions on a tonearm new or used on a $1000 budget (max) that will out perform my modifed RB-300 with drop counterweight, VTA adjuster and VdH wire.

The cartridge I use is a Grado Reference so it will have to be lightweight to limit that infamous "Grado Dance". I also use a Golden Cross phono cable and the table is similar to a Linn Sondek

I thought maybe Hadcock or Morch because their light but thats pushing the limit if bought new.

Any other suggestions would be helpful.
