Item: Rega stylus guard. Assuming one from any of the 2m range would work (i.e. blue, red, black etc.)
Price Range: $5? These are included with all carts and most people never use them!!
Item Condition: New or Used
Extra Info: I accidentally snapped mine whilst mindlessly playing with it. I like having one on as I am less scared about the kids being in the room without me around if I have it attached (i know it's not bomb proof - but every bit helps).
