Some usefull information in this thread.
I use ebay like its my own shop. I start my auctions every wednesday/thursday night for 10 days, so they end on weekend evenings and overlap the previous weeks items.
Hopefully this get's a following.
I post alot of photos (hosted off site), post a velobase link and start at a reserve style price.
In this case, 16 euros.
I try and post one campagnolo item per week, to try and get people to see my other less seached items
