Ebay dual listings have been awesome, that's where a majority of my stuff sells, would be cool if the listings were ebay promoted once in awhile to gain even more traction.

If I were you, I would really push to get sales on eBay so you can get more customers, once you have their info you can target more individuals like them. I know the goal is to get people on the website directly, BUT this is a way to get the word out. Think more long term, ebay is a great way to find customers, once they buy once, they will most likely buy again.
