Have you considered EZ-Upsell? It's "related" to eZrecommends (cousin ?), but instead of upselling at checkout, it upsells at "add to cart". To me a "softer" upsell, and usually more relevant. By the time a customer decides to checkout, in my opinion, the primary upsell opportunity has passed. I think ez-upsell is one of Jon's "must have" mods. It's 4.1 savvy. I gave it 5 stars!
