Buy the Rega and put a Grado on it if your objective is to buy once and be happy for a long time. I sold every moving magnet made a number of years ago (Before Benz Micro was in market) Grado was then the best MM, followed by Goldring. The Dual is not a good TT and will degrade your sound. Its only virtue was that it was a step up from the Pioneers and Technics made in the 70's and 80's. Shure cartidges while they track well have a dry antiseptic sound whereas the Grado's have great base and excellent mid range tonal color.
