700 Mountain rifles are great guns. Just about as perfect a hunting rifle as there is, at least in my mind. Light, compact, accurate... can't ask for much more. I have 2, and love em.
The LSS is pretty sweet. I would start calling around, I bet someone has them. Last august I saw several in gun stores. I would also keep an eye on the auction sites. Gunbroker seems to have them occasionally. You'll find one for sure if you look hard enough, and are patient enough. And of course, you can always get the new model mountain if you can't find an LSS you like. Its SS gun w/synthetic stock. Another good option is the LSS model 7.
