I've seen them go there for anywhere from $60 to $120 dollars.
It just depends on how bad someone need one at the time.
There is one there right now. The last time I checked it was a little over $60 with almost two days to go.
They are always popping up on e-bay. Buy it now prices are usually about $100.
I really need one of those. My machine is about eight feet from the console. It's a real pain when I'm mixing. Up and down after every pass.
