That's about what I paid for my 1066, although mine had some holster wear from LEO holster use. The price is right, especially if it's in good shape.
General consensus seems to be that the 10xx-series Smiths are among the best pistols ever cranked out by *&*. Reliable, solid, well-constructed, flat, and easy to shoot...although they are a tad on the heavy side if you're used to toting a polymer autochucker. The 1066 weighs in at 39 ounces, not a lightweight...but it's very easy to carry in the right holster thanks to its slimness, especially in the grip area.
10mm is a great caliber, powerful and versatile, and the 10xx-series Smiths are very good platforms for it. I'd get it in a heartbeat for that price...they only made the 1066 for two years, between 1990 and 1992, and they sure won't be getting any more common in the future.
