Where can i find a Monitor for a Vermeer 504L baler?

Our monitor for our Vermeer 504L baler was ruined after the cab on one our tractors leaked recently, I need to find another One ASAP. Any ideas where we could find reconditioned or used one at a reasonable price? Have priced new one thru Vermeer dealer, would like to see if there are any other options out there. Any help wil would be greatly appreciated, thanks.
