Edison Phonography Model LU 37

Can anyone give me an estimated price for a fully operational Edison Phonograph in excellent condition. The model # is LU-37.

I think this is a fairly easy to find Edison with limited collector demand, but I am new to the phonograph hobby so I won't give you a number.

The LU 37 when introduced sold for $100. The top of the line Edisons sold for $250+
