Sure you want DD TT?Have you heard a decent Belt Drive to compare?Yeah you have potential of less peed acccuracy but with a decent belt drive you have less rumble and a new maybe better experience/For price of replacement arm.Ask movers for cost of replacement and check out a Rega,VPI or other deck that would equal price of arm more or less.Jelco 9" is nice but will set you back $500 or so.Just a thought.
