The big internet auction site has several with box and manual at a starting price of $500 to $525.

Last year, I bought a stainless CS40 with one extra mag for $425 that was in mint condition without the box. Yesterday, I picked up an all blued CS40 that appears to be 80-85% with one mag for $280.

I find that gun buyers follow trends like the car or stock buyers. Today's ugly duckling is tomorrow's darling, so I see the out-of-favor .40 caliber pistols as a buyer's opportunity. We seem to be rotating into .380 now.
