Hi, I have being selling parts and parting out stuff I come across for over two years. I used ebay for a wile but it is very expensive and there are major restrictions that will keep you from selling all your parts (plus you will fork over a large % of your sales for it ... it has been up to 18% for me).
Craigslist means an inbox full of the same questions over and over and 5% of the requests being actual offers, but still you are going to be wasting tons of time on unqualified offers sifting through to find the few that are serious.
I have one parting out listing on PartingOut.com a site I found on another forum and it works much better if you are parting out a whole bike. One big reason - you don't have to list every part. I list the top ten parts like I usually would but then the buyers use the Buyer Listed Part tool to list the other parts I didn't list that they want.
I have sold about ~$600 worth. There are only three bikes up right now, I think they just added the bike section ... but I have sold some top parts but its been the uncommon parts that I keep selling. Never did I think i would sell those little parts but when buyes can list it themselves and then just say I'll give you X$ for it... ok! Illl take it!
Anyways trying to help us all out and get off the ebay craiglist trains cause they don't work and cost way to much time and money
