The only thing about my new PX-560 that disappointed me was the pedal. Personally, I think it looks naff; more importantly, I found it too easy to knock it sideways, or even to the back of the keyboard, it is so light.
I ordered an M-Audio SP-2, which cost me all of 12 quid. Just picked it up from Amazon Lockers, and I am delighted with it. It has some weight, stays where it is put, and it also looks the part. I am also finding it with my foot easier, without needing to shuffle around down there.
So now, largely out of curiosity, I check eBay for what Casio SP-3s are going for, and am surprised to see the going rate seems to be 12-15 quid, more than I paid for my "better" replacement.
Am I missing something?
(While I was at it, I also picked up M-Audio's Expression pedal. I don't have a use for it yet, but probably will do, once I am more aquainted with the piano.)
