What is the best Shopify app to import eBay orders without mapping?

[Woodchuck]

I've got an Etsy store, and I loaded the "Shuttle" app, to load my Etsy orders, into Shopify. Shuttle  does this perfectly. I don't have to map any products. it simply loads in my Etsy orders. I sure with they also integrated with eBay.

So....

Does anyone know of a Shopify app that will do the same with my eBay orders?

eBay has a Channel, but in order for that Channel to bring in eBay orders, all of the products I'm selling on eBay have to be mapped to current Shopify inventory....no-go.

I just wanna load my ebay orders, into Shopify. Plain and simple. No mapping. No fuss, no muss.
