My thoughts exactly, this is just getting ridiculous and I am glad to not really be a major pedal collector, cause if I was, I probably wouldn't be now anyways...
They've just about tripled in price in less than a year.
They could come back down, though -- HR-2s were going for around $150.00 earlier in the year, but now are usually less than $100.00. I'm guessing that CE-1s in decent condition will back off to $500.00 and hold there.
