It's a good price for an example this nice. It's not mint by any stretch but its certainly one of the better ones. The pop-out hood is included. Add $15 for a nice lens board.
I have a few lenses in the 150-180mm focal range... 162mm Optars, 165mm and 180mm CZJ Tessars, 150mm Apo Symmar, 180mm Symmar-S, 152mm Ektar... to name a few. Are you trying to stay within a budget? Are size and weight of any concern? Any particular vintage you want? Is maximum aperture important?
