On the other hand me and my family have picked up up several Monsters including an S2@ that were totalled with tank scratches and handlebar damage.
Lemme think.
Got Krystals 620, it had bend bars and the steering stop bent, I think $1,200.
Got a S2R outta Georgia
Bent bars, scratched tank, and needed a crankcase cover. $1,600.
If you know bikes and know what you're looking at you should be fine. As always look at the over-all conidition not just the wreck damage. If chain and sprockets look worn, or it has multiple rashes that look like they've occurred at different times you're probably looking at a abused specimen. I can send you pics of mine if you need and example.

On the other hand if it's clean and garaged and relativiely nice minus the damage you can prolly get a great deal on a bike that will treat you well. Look at it like you would a dog adoption. Does the seller have other bikes? What condition are they in? Where are the bikes kept? Look around you the environment can tell you a lot.
