eBay has scams as well and some dishonest people who will claim the item is not as described then ask you eat shipping both ways so you can get the item back. If you are lucky, you'll get the item back in the same condition. eBay is also tends to side with the buyer in most dispute cases which worries me. I just use eBay for the easy to ship items.

Craigslist takes awhile, and has a lot of low ballers, but if the item is priced right, it does sale. Most of the items I sell are low to mid end so not sure how hard a higher end bike would be to sale. I know when I bought my mountain bike, I had the seller meet me at a bike shop and had them look it over to make sure nothing major was wrong before I even test rode it.
