In our store we show the Nottingham Space Deck and Space Arm combo with a Dynavector 17D2 which is a great cartridge for the money ($750) and a common upgrade is to the XX-2 ($1650) which is a superb cartridge regardless of price. The Helikon is also an excellent choice but it is priced higher than either of the Dynavectors. The XX-2 is really superb and carries what I think is a very reasonable asking price given its extremely high level of performance
