Did you see what it ended on? There's usually frantic activity the last few minutes so I bet it ended a lot higher than $28 (or maybe the credit crunch is starting to affect the guitar pedal market now).
I don't know if it's the same one you're talking about, but one sold for $42.01 US dollars last night (12/9/08). I almost went for it but the seller didn't provide any pics showing the "made in Japan" bottom label nor provide a serial number, so I was suspicious. Someone asked him for a serial number but he didn't provide it, only said it was MIJ. Hope the buyer got what he thinks he paid for!
