I guess that all would depend on the condition of the bike and how complete it is. Cat parts are not the easiest thing to find. So if you start with a pretty complete bike thats half the battle. If the bike your looking at is missing say fenders, switch plate, clutch cover, brake, kickstand etc.you could be searching for awhile and spending some serious green when you do find it. That is if you want to restore it back to as close to original you can. A bike missing all the parts i mentioned, basically a roller or with a motor i wouldnt give any more than 100 to 200 .
