TheFind is going to be less volume because all sellers are listed there. TheFind crawls the internet and attempts to list every single product online, which means more competition for you.
I would suggest Bing Shopping but it is for US retailers only.
Have you tried paid comparison shopping engines before? Can you ship international? There are high ROI paid CSEs and international Google Shopping channels you could list your products on for free.
