What's a Century 3000 worth?

I replaced the glass, gasket, and fire brick on the Century. My neighbor wants the Century in exchange for some drywall work. The Century is in good shape. I have no idea what it's worth. Anything half way decent on CL here go for $400-$500. I bought a new BK. I purchased for $650 in 2005.

If it is relatively low mileage and in good, clean condition then $4-500 is a good asking price.
