You're looking for a seller who simply wants to get rid of the bike, whether it belongs to him/her or not, or just tired of having it around, things like that.
Unfortunately, stolen bikes also fit into this category, so watch out for a "too good to be true" deal you roll up on.

3-CL. The boonies. Look for ads in places a bit of a drive away.

4-Networking has been covered. Can't say enough about that. Simply can't. It works. Get the word out.
Company bulletin boards are great, if they still exist. Seems like every other person has an old bike they want to get rid of.
Once in a while, you find a good one.

5-Other cyclists, especially middle-aged men with new bikes. Seriously.
