Best Affiliate Software for 1shopping cart?

Hey guys,

We're currently about to launch a new wordpress site and are going with 1 shopping cart for our store. I know the more expensive version of 1 shopping cart has an affiliate program, but does anyone know a better alternative? (cheaper/better features, etc)

Please list your suggestions

thanks,

Julian
