I own a Sonor Giant Step single pedal. I bought it slightly used(pretty much brand new) from someone on the Sonor Forum for $150.00 including shipping. I have played Axis, Iron cobra, DW and I think the Sonor has feel that is a cross between the DW 9000 and a Axis pedal. The Iron Cobra alway felt a bit sluggish but I don't really have a fast foot. I love the docking station, to me that is one of the coolest things about the pedal. Similar to all high end Sonor stuff the construction is bomb proof. When I bought the pedal I was thinking of getting a Taye Metal Works or DW pedal but then I came across the Giant Step for $150.00 and couldn't pass it up. Hope this helps!
