Mapex P600 Mars Bass Drum Pedal

My standard drum pedal for my Gretsch Renown Maple drumkit is a Pearl P-2000C PowerShifter Eliminator Chain which I love. Recently I purchased a Roland TD11-KV electronic drumkit to study and practice at home without disturbing the neigbourhood. The first weeks I used the Pearl but finally decided it would be more practical to get a second drum pedal for the Roland. With a priority list featuring "maximum 70 Euro", "must have a base plate" and "must have a plastic beater in order not to damage the surface of the Roland bass drum" I ended up buying the Mapex P600 which is OK for the job but a trifle too noisy even after having checked all parts and having applied some machine oil.
